The game seems a little short. Maybe add new characters with different personalities and have it like a tournament style in a future iteration. The aesthetic and sound design of this game is really nice. (I am not very good at either of those)
I had the same idea too, but I wouldn't have had time to produce art for them hahaha~ but I might do so in the future like you said. Thanks for trying the game out! I was honestly a bit unsatisfied with the sound effects because I just hit random on bfxr so many times till I get a good sound :P
