Look and animations are great! The enemies remind me of Monster Kid from Undertale.
I beat the "Boss" but there is barely any visual or audio feedback for doing anything. No HP also means it doesn't matter if anything attacks you. Music didn't loop, which is a shame, since you created it yourself.
Would have liked to play a more fleshed out game but that's just the nature of GameJams. Our Game didn't give us time for a proper ending either.
