Really fun game! Some of the sprite work gave me a sort of GBA Fire Emblem vibe, which I don't say lightly! Gacha+deck building mechanics really fit with the theme, and is something I don't see much in this type of low-res retro projects. Not sure if you intend on working on this further after the jam, but some bgm + sfx would really make this project shine, IMO. Very nice job!
