    92 mentions Positive Neutral Negative

    The gameplay is praised for its unique mechanics, particularly the hacking and puzzle-solving elements, which provide a satisfying and engaging experience. While some players find certain mechanics, like lockpicking and parkour, frustrating or buggy, the overall level design and variety of challenges keep the gameplay interesting and enjoyable. Many reviewers express a desire for more content and expansion of the game's concepts, highlighting its potential as a polished full game.

    • “With its incredible level design and unique ideas, High Entropy: Challenges gives multiple ways to solve each level, whether it be killing bots, sneaking past them, or even taking a moment to appreciate its fresh take on the hacking mechanic.”
    • “The gameplay is sufficiently detailed to be the sole driving force for this kind of game; doubly considering the fact that this is more of a test run than the actual finished game.”
    • “From the moment you start playing, you'll be hooked by the game's intricate puzzles and exciting gameplay mechanics.”
    • “As if the jump is not as effective and the ledge grabbing mechanic occasionally goes haywire and forgets it actually needs to function.”
    • “The lock pick mechanic still is frustrating, but other than that the game is good.”
    • “The computer mechanics feel a bit... shallow.”
  • graphics
    40 mentions Positive Neutral Negative

    The graphics of "High Entropy: Challenges" receive positive feedback for their immersive and aesthetically pleasing design, often compared to titles like "Splinter Cell" and "Portal." While some users note minor optimization issues and a slightly outdated look, the overall visual presentation is praised for its charm, retro computing aesthetic, and effective atmosphere that enhances gameplay. Many reviewers highlight the game's ability to balance good graphics with engaging mechanics, making it a standout indie title.

    • “The night vision effects look absolutely amazing; this game is basically on the same level as the Splinter Cell series. Not many games achieve this quality, and many other graphical designs are also comparable.”
    • “Awesome graphics, interesting and unique puzzles, along with first-person shooter mechanics that feel fantastic.”
    • “The atmosphere and graphics are pretty dope, and I love the sound design and retro computer aesthetics.”
    • “I had to tune the graphics down somewhat else my fans would spin at 100 even though I don't really see why (optimization?), but that didn't matter one bit.”
    • “The graphics are neat, but nothing special.”
    • “Optimization and graphic bugs.”
  • story
    27 mentions Positive Neutral Negative

    The game's story is largely criticized for its lack of depth and coherence, with many players expressing a desire for a more fleshed-out narrative to accompany the engaging puzzle mechanics. While some appreciate the potential for storytelling through environmental elements and themes, the overall consensus is that the game feels more like a series of levels than a cohesive experience. Players are hopeful for future updates that might introduce a richer storyline and more immersive elements.

    • “I really enjoyed High Entropy; it's a really good game. If this was $10, I'd buy it. The story really rocks, there's 2 endings, and it's a really challenging game. I looked at some videos when I had problems with levels; I didn't even rage at all in this game. The graphics are really nice.”
    • “It has good graphics for an indie game made with Unity, and the game has a rich story which I instantly fell in love with and got addicted to. I liked the concept with the old Commodore 64 computers from the 90s and 80s; those were a good touch, not gonna lie at all!”
    • “Just play it and you'll see what I mean - imagine it all whistles & bells - high-def graphics, enticing character story-line, and so on.”
    • “With not much story or plot component, the game puts you in puzzlebox levels with multiple solutions and lets you have at it.”
    • “On the downside, it lacks even the light plot and setting that those games had, and more importantly their tight controls.”
    • “Good game all together but sad to see not much story, I was very interested but when I got in the game there wasn't much after that.”
  • atmosphere
    11 mentions Positive Neutral Negative

    The game's atmosphere is highly praised for its immersive qualities, drawing comparisons to titles like Portal and Prey, with a unique blend of post-WWII sci-fi and retro computing aesthetics. Players appreciate the effective use of music and sound design, which enhance the overall experience, although some find certain design elements, like the robots, to be somewhat cartoonish. Despite minor criticisms regarding challenge and monotony, the atmosphere remains a standout feature, creating a sense of loneliness and tension that captivates players.

    • “The music and sound effects are also perfectly suited to the game, adding to the overall atmosphere and immersion.”
    • “Even in its most difficult (or frustrating) moments, I was still completely immersed in the post-WWII American sci-fi-inspired atmosphere it brought to me!”
    • “The whole 'retro computing' aesthetic is done wonderfully here; the portal-meets-the-Iron-Giant atmosphere doesn't feel forced and, when the robots loom towards you, it can get pretty terrifying (in a 'oh, god, I'm about to die if I don't get this door open!' kinda way).”
    • “I really liked the atmosphere of the game, but it wasn't challenging enough, and a bit monotonous.”
  • grinding
    10 mentions Positive Neutral Negative

    Players find the grinding aspect of the game to be tedious and repetitive, particularly in relation to puzzle-solving and computer tasks. While the puzzles are engaging, many reviewers noted that certain elements, like the nightvision goggles and hacking sections, add unnecessary complexity and boredom, detracting from the overall experience.

    • “You'll need a second life for grinding.”
    • “Tedious garbage”
    • “A well-made game, but the puzzles feel samey and tedious after a few levels.”
    • “I rate this an 8/10, mainly due to many tasks being tedious and somewhat making the level really boring.”
  • replayability
    6 mentions Positive Neutral Negative

    Overall, the game offers solid replayability through secondary objectives, achievements, and multiple completion paths for each level, allowing players to explore different strategies and endings. While many players appreciate the potential for increased replay value, particularly with the prospect of a level editor, some note that the variety in endings may be somewhat limited.

    • “It's highly replayable too, since each level can be completed in a number of ways to achieve a 100% rating and see the true ending.”
    • “The different endings mean it has some replay value, although it's pretty limited in that regard.”
    • “I took my time with it and I spent 4 hours completing it, and there's still some replay value since I didn't complete all the achievements.”
    • “It seems this is a test for another game, and I can't wait to see the final product, especially with a possible workshop/level editor for increased replayability.”
  • optimization
    6 mentions Positive Neutral Negative

    Overall, the game's optimization has received significant criticism, with players reporting severe lag, high fan usage, and graphical bugs that detract from the experience. Many users noted that even with decent hardware, performance issues persist, particularly related to physics and camera behavior. While some aspects like graphics and audio are praised, the general consensus is that the game requires substantial optimization improvements to enhance playability.

    • “I had to tune the graphics down somewhat else my fans would spin at 100 even though I don't really see why, but that didn't matter one bit.”
    • “When I first started playing, I already could notice that there is something wrong with the camera. It's almost like it teleports a little bit instead of just following you, almost like the game is lagging, even though everything else is running at 60 fps. The optimization is quite poor; I have a GTX 1660 Super and a very good processor, and my computer still starts heating.”
    • “Optimization and graphic bugs.”
    • “The game could be optimized better though; I think the physics is what really slows the game down.”
    • “Also, your game is extremely unoptimized and lags like crazy.”
    • “When I first started playing, I already could notice that there is something wrong with the camera. I can't explain it well enough, but it's almost like it teleports a little bit instead of just following you, almost like the game is lagging. Even though everything else is running at 60 fps, when I turned Vsync off, I was literally getting dizzy. There are other bugs, but they are very minor and won't affect the gameplay that much. For example, if you look at a wall and then look to the side to a point where you can only see the wall on the corner of the screen, some walls will visually disappear. Besides that, the optimization is quite poor. I have a GTX 1660 Super and a very good processor, and my computer still starts heating up.”
  • stability
    5 mentions Positive Neutral Negative

    Overall, the game demonstrates good stability with easy-to-use controls and minimal bugs, particularly in the free version. However, some users report occasional issues with the 'climb' mechanic and combat, which can detract from the experience, especially as gameplay becomes more demanding.

    • “The 'climb' mechanic is a little buggy sometimes.”
    • “Buggy combat.”
    • “But the game is buggy and demands perfect gameplay after a certain point, making it not very fun.”
  • music
    5 mentions Positive Neutral Negative

    The music and sound effects significantly enhance the game's atmosphere and immersion, with many players appreciating their quality. However, some users noted the absence of music in certain sections, expressing a desire for a more complete auditory experience in future updates. Overall, while the puzzles are well-received, the lack of music in parts has left some players wanting more.

    • “The music and sound effects are perfectly suited to the game, adding to the overall atmosphere and immersion.”
    • “It's really challenging, but I missed the music so much.”
    • “Waiting for the full game, story, voice, and music!”
  • humor
    4 mentions Positive Neutral Negative

    The humor in the game is appreciated for its quirky achievements and the absurdity of certain mechanics, such as the protagonist's inability to break glass with punches, which adds a comedic twist to gameplay. Players find the combination of retro aesthetics and bizarre combat mechanics amusing, particularly the humorous synchronization of character animations with beep sounds in lieu of voice acting. Overall, the game's humor contributes to its charm and enjoyment, despite some inconsistencies in combat mechanics.

    • “For what little of it I've completed, I have enjoyed the humor in the achievements, the thinking that the puzzles made me do, the aesthetic of the game's environments (I'd describe it as a mix between a 70's office building and a modern horror hospital), and generally I think it's pretty fun.”
    • “Also, the fact that the speaking animations are synced to the beep noises that replace actual voice acting due to a lack of actors is bloody hilarious.”
    • “The combat, at first, looks simple; you are the weakest human being on earth, unable to damage anything with your fists. It's funny because if you throw a soda can at the glass, you can break it, but throwing a punch can only break already broken pieces of glass. It's weird but fair enough, giving that if you could, some levels would be way too easy.”
  • monetization
    2 mentions Positive Neutral Negative

    The game is praised for being completely free and lacking microtransactions, which users feel is a deserving approach to monetization. Overall, players appreciate the absence of financial barriers in enjoying the game.

    • “You deserve some kind of monetization for it.”
    • “To start off, this game is phenomenal for something that is completely free and has no microtransactions.”
