cool game. great artstyle and audio. the controls were surprisingly intuitive and it's making me rethink the arrow key norms. that being said the controls sometimes felt a little unresponsive, and the platforming got a little frustrating.
some advice: quicker respawns, when you fall out of the world it takes far too long to respawn.
don't stop the music on death. if you keep it looping even after you respawn it makes it feel like death is apart of the game, causing less frustration.
maybe clamp the camera to the top of the level, it'll make platforming easier because you'll be able to see platforms and enemies under yourself, and it'll stop you from seeing where the background ends.
overall cool little game and i do think there's a lot of potiental here
