Wow, a bot autobattler with component parts. I love it, impressive for a jam submission! You did a good job working with the simplest of art assets to create a cohesive experience. I would maybe avoid the trap of "let's play a different music track for each different screen the game has" when those phases are very quick, particularly the "stage selection" screen, but I like the music you went with.
This is very creative, nicely done!! :)
