The music in the game has received widespread acclaim, with many reviewers praising its pulsating synthwave soundtrack that enhances the overall atmosphere and immersion. Players appreciate the blend of sci-fi themes with the music, describing it as a standout feature that elevates the gameplay experience. While some suggest the need for more variety in the soundtrack, the consensus is that the music is a significant highlight, making the game enjoyable and addictive.
- “Great music and presentation.”
- “The presentation is gorgeous while maintaining remarkable readability and the pulsating synthwave soundtrack absolutely slaps.”
- “The pulsing synth soundtrack deepens the sense of immersion, reinforcing the atmosphere of a desperate futuristic skirmish.”
- “I mute most of my game's audio and have my own music run in the background, but this game is one of the few exceptions.”
- “Great visuals, runs smooth, I hope we get more music as it feels a bit repetitive even when selecting random and a map overlay or HUD.”
- “The game is a decent 'survivors' clone that has a unique visual style and varied and fitting music selection.”

The graphics of the game receive mixed feedback, with many praising the overall aesthetic, art style, and smooth performance, particularly in dynamic environments. However, some players criticize the enemy designs as lacking detail and the art style as occasionally flat or generic. Overall, while the visuals are generally well-received, there are calls for improvements in enemy variety and graphical clarity during intense gameplay.
- “The art style is amazing and I enjoyed the enemies and bosses, especially the final boss.”
- “Amazing visuals, you will fall in love with how the character travels on the map, the friendly camera angle, the fog giving you that danger feel, occasional lighting strikes revealing the location and how the weapons interact with the mobs.”
- “The graphical style, dynamic levels with optional objectives, cool and powerful selection of weaponry, and an absolutely incredible synth soundtrack from Cartridge 87 pulsing through your headphones, it's a hugely rewarding experience.”
- “The graphics are a mix of mostly 3D maps and player and 2D sprites as enemies.”
- “The art style is kind of flat and generic, and the mushy filtering makes it difficult to see what's going on at times.”
- “I see it probably needing some quality of life improvements as well, like effect opacity so enemies wouldn't get hidden behind all your projectiles' flashy effects, better explanation of graphic settings (what does 'cinematic' quality actually do?) or just giving more granular options to change it as we like.”

The gameplay is characterized by familiar mechanics reminiscent of "Vampire Survivors," featuring both auto-fire and directional weapons to combat alien foes. While it doesn't reinvent the genre, it offers a satisfying loop with responsive controls, stylish visuals, and a rewarding progression system, making it enjoyable for fans of the genre. Despite some generic elements, the overall experience is enhanced by a killer soundtrack and engaging creature design.
- “Nice interpretation of the usual bullet-heaven/survivor-like mechanics.”
- “Killer soundtrack, looks and plays great, creature design is rad, maps are fun, and has a pretty satisfying progression and fun mechanics for anyone who enjoys vampire survivors, Brotato, etc. New characters and weapons on the way.”
- “Gameplay is mostly the same as Vampire Survivors; you kill aliens using auto-fire omnidirectional weapons or you position yourself carefully using the few weapons that only fire in one direction at a time, like the hammer or the laser in the direction you're facing.”
- “However, its game mechanics, level design, and progression systems are very generic.”
- “It doesn’t attempt to reinvent survivor-style gameplay, but what it does offer is crafted with care: tight pacing, responsive controls, stylish presentation, and a progression system that makes each successful run feel earned.”

The game's story is minimal, focusing primarily on survival and completing random missions within a set timeframe, which some players find acceptable as it allows for personal storytelling. However, there is a desire for more narrative depth, including character backgrounds and context for the alien adversaries. The randomness of missions and events adds unpredictability to each run, but can also lead to frustrating gameplay experiences.
- “My ongoing quest to find a sci-fi-themed game in this genre I can stick with may have ended with this one.”
- “Oh, I will also say some story/exposition stuff would also be nice, some background on the characters and the aliens they're fighting.”
- “Each run unfolds slightly differently depending on which random missions and side-objectives appear, giving the experience a welcome layer of unpredictability.”
- “Even if you pick one of the other characters to play as, the story seems to remain the same each run. You need to survive around 18 minutes, fight a boss that appears in the last 2 minutes, and then a nuke drops and you die anyway.”
- “Event and main mission spawns are also completely random - once I had a mission from the start of the level where I had to walk for 10 minutes straight to reach the destination (while also being bombarded by events that I couldn't complete because I had to keep moving towards the mission).”
- “The flow during the mission wasn't thought through either.”

The game's atmosphere is highly praised for its immersive quality, enhanced by a pulsing synth soundtrack that effectively conveys a sense of urgency in a futuristic setting. While it may lack in weapon or item variety compared to other titles, the overall ambiance and music create a compelling experience.
- “Really good stuff, great atmosphere and music.”
- “It may not have the weapon or item variety of a brotato, however, when it comes to atmosphere, this game knocks it out of the park.”
- “The pulsing synth soundtrack deepens the sense of immersion, reinforcing the atmosphere of a desperate futuristic skirmish.”

The game offers high replayability due to its short runtime of around twenty minutes, making it easy to engage in quick sessions or extended play. Users appreciate the potential for varied experiences, suggesting additional elements could further enhance replay value.
- “Runs last around twenty minutes, which makes the experience highly replayable—easy to pick up for a short session, but also easy to binge for far longer than expected.”
- “Would add another vector for replayability, maybe.”
- “The game lacks enough variety to encourage multiple playthroughs.”
- “Once you've completed the main story, there's little incentive to return.”
grinding

Players appreciate the grinding aspect of the game for its casual, mindless fun that allows for easy pick-up-and-play sessions, especially in groups of up to four. While the demo progress does not carry over, many are willing to grind again, with some completing normal mode in about eight hours and looking forward to future content expansions.
- “I can see this gameplay being viable with up to about 4 people in a group, but half of the appeal of the game is the simple, mindless grindy fun you can pick up and put down whenever you feel like.”
- “It sucks that the progress from the demo doesn't carry over, but I have no problem grinding again.”
- “Fairly short for now; with casual grinding, I finished normal mode in 8 hours and will move onto hard mode. The developer has already said this is just the beginning, so I'm looking forward to more weapons, levels, and characters!”
