actually something new in the gacha landscape. It is a mix of darkest dungeon and slay the spire. fast animation and combat means you dont need a 2x or 3x speed-up (it doesn exist). Fun gameplay, easy to play but hard to master. The gacha itself is also very forgiving with soft and hard pity and if you dont get rate up character, you keep the soft pity progress. the bad thing is the faulty translation and no skip function for dailies. i have removed a star due to thw constant disconnect issues.

You guys made such a damn good game! The dungeons are so fun, especially in Nightmare mode. Whoever came up with the epiphany system, give that person or team a raise. The fact that you can build your characters in so many ways, is just amazing. EDIT: I've noticed a trend with the new characters, you guys are creating a problem, then selling us the solution in the form of duplicates for the characters. I really don't like that, it's kinda lazy, and feels scummy.

Very fun game. The characters, story, and battle mechanics are very well done. The only issues I have is that prism lens are scarce and difficult to obtain as far as I know making it harder to get animated cards for 5 star characters. I didn't like that everything is locked behind your commander level. Its a tedious thing to have cause I enjoy upgrading my characters. Also hope to see a balance of male and female characters added to the game. Overall great game and would recommend to anyone
