I bit the bullet to write this review, I went into this game with very low expectations considering this game admits to being "100% AI driven development". It is as bad as the label states. This game is unoriginal AI slop masquerading as a real game. Don't waste your money on this, instead you should buy a fast food burger. Because at least you'd get your money's worth and be more fulfilled.14 found this helpful
Great game with excellent developers. I'm still in early hours playing this, but I love it.1 found this helpful
a Good Challenging game.1 found this helpful
The game has some very creative synergy mechanics that makes it super interesting to create builds... It also has a good progression mechanics, including for very late game, I'm a hardcore player so I like this combination to go for ever higher difficulty levels... And it's nice because there is end-game progression as well, so you are always improving. It also has additional heroes that act as companions, which expands your opportunities, like leaving one of them just to apply curses, etc... And also, artifacts, which acts as another layer of customization to create different builds... Pretty good game overall IMO!
This game is great! Great value for the money and plays well. Building your character with new skills and synergies is a great way to play same maps and try new fun builds for harder difficulties.
Very fun, got totally sucked in and played nonstop for 3.6hours. I don´t get why people hate Ai. All inovations steals job. How come everyone reacts so heavily to this. if you can create good games with Ai I´m all for it. + Good music + 1-4 co-op palyers Adopt or die, Be a mammal or become a dinosaur. Ai is a tool so far so why not use it while we still are in control of it. In 2 years we probably don´t have a thing to say about it anyway hehe. My hope is that Ai in games are focused on dialogue and open rpgs with endless possibilites to aproach on goals. Anyhow. Quite fun game and I strongly recommend to try it out. Graphics are quite okey and it´s not worse than some other indiegames in anyway. Posted 19 December, 2025. Last edited 19 December, 2025.
