  • monetization
    87 mentions Positive Neutral Negative

    The monetization model of the game is generally well-received, with players appreciating the lack of forced ads and the option to watch ads voluntarily for rewards.

Overall, while the game allows for free play, many players recommend purchasing the ad removal option to enhance the experience.

    • “It's a unique idle concept, and a fantastic game; I just wish progress was a bit faster and in-game purchases weren't the driving force behind efficiently improving and advancing through the game.”
    • “At first, I didn't like how slow the progress was, but after playing for a while and only spending some money for no ads, I was able to unlock the last character early.”
    • “This is a great game with no ads unless you want to watch an ad, but we need more games like this, and this is a great idea from the creators.”
    • “I don't like how earning the other villains takes absolutely forever and the in-game purchases seem a bit pricey.”
    • “This game is really focused around in-app purchases... within a couple of days I was unable to progress without a $10 purchase for a new villain.”
    • “After watching ads, the game crashes without giving promised rewards.”

    • “It's clever and the dialogues are well written and humorous.”

  • gameplay
    43 mentions Positive Neutral Negative

    The gameplay is characterized by clever mechanics, engaging dialogue, and charming pixel art, making it enjoyable for fans of idle games.

    • “My biggest praise for the game is how easy it is to get started and how you grow as you learn both mechanics and strategies.”
    • “A satisfying loop of very respectful to your time gameplay, mixed with many different options that keep unfolding the more you play paired with one of the most responsive and considerate developers out there makes this a game you will not want to miss and which I know I will keep returning to every single day for years to come.”
    • “Engaging gameplay, layers of strategy, well thought out design, great art/music, and a good dose of humor (without being silly).”
    • “A funny game, but its humor is the main part; the gameplay is pretty boring, but the word 'idle' in the title makes that obvious.”
    • “Most of the game mechanics are geared around real-world money and lots of it.”

  • story
    20 mentions Positive Neutral Negative

    The game's story is generally viewed as entertaining and humorous, with a well-crafted world that adds to the overall experience. However, players note that the narrative can feel basic and is hindered by grinding mechanics that slow progression, particularly in unlocking additional storylines and essential gameplay elements.

  • grinding
    17 mentions Positive Neutral Negative

    The grinding aspect of the game has received mixed feedback, with many players noting it is significantly more grindy than previous titles from the developer. While some find the grind engaging and a way to extend gameplay, others describe it as tedious and frustrating, often feeling like a chore that detracts from the overall enjoyment. Overall, the grind is seen as excessive, leading to repetitive playthroughs and a slower progression that may deter some players.

    • “However, this title takes that to a different level, because not only is everything unlocked by grinding, the shop doesn't allow you to buy things more than once.”
    • “I was told I could unlock a new one after my first reset, but that was a lie because I needed one thousand of a material that is so hard and tedious to get.”
    • “The grind escalates far too quickly, leading to tedious playthroughs that make little progress and have no variation from previous runs.”

    • “I love the art direction; the sound design and music production are always top notch.”
    • “The soundtrack is outright bangin.”
