The game feels polished with things like the enemy knockback, the flashes, the sound effects, etc. and the gameplay style is fun, but the core idea is a bit confusing. It's not really explained what the percent below the fox is (I think a 2nd health?) and why it randomly decreases. And also, I don't really know how it relates to the theme of the game jam other than the idea of enemies being bats, but it's not even in a cave or anything. The setting looks like it's just above ground, so why are there bats everywhere?
So basically: technically, the game is pretty good but the idea itself needs a bit work
