Honestly this is a pretty cool game. Gameplays fun, the art is cool and the music is a banger.
One small nitpick that I have is that I feel the characters could use more unique stats, like one rare character could have a higher offense but lower defense compared to another rare character, maybe even some characters can gain more or less energy points per turn for a bit more variety. I'm not that bothered though, the current way is fine enough.
Either way, very solid game!
