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. You had a few hiccups at launch, but you communicated and got them fixed. The game isn't easy, it's very challenging in a good and addicting way. Keep it up devs. 👏👏👏

This game is absolutely incredible. In all aspects almost. Graphics, animations, sound effects, music, progression systems, combat gameplay. All 5/5. Story is also pretty good. The reason I gave it 4 star is because there are some pretty ridiculous bugs that need ironed out - such as suddenly not being able to target anything. Also, the text translation while overall pretty good, has some major issues with gender accuracy. A single character may be called he, her, they all in one dialogue scene

so after a few days of play I can say the game itself is fun, the characters are very well done. The rewards from simulation are kinda low but it's fine not to bad. The actual gameplay is pretty strategic as certain card setups benefit certain character play styles. My only real gripe is the constant connection loss, the main reason I uninstalled the game. Hopefully they fix there servers then id bump it back to 4 stars. Great game id recommend giving it a shot.
