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.

Update 02/2026: The longer I've played, the more I feel the director's interference with the game's identity and story is actually working as intended for them and not for those drawn by the potential mature vibes brought by the notes of horror and despair. The game still looks and plays well, but the data mined images and mentions of how dark the old story would be makes the reach for a wider audience more apparent. I'll just take this as the game no longer being what I wanted.

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
