Having the player as a cloud was definitely among the first ideas I had when I saw the theme and restriction of this jam; but I didn't know what to do with the concept so I buried it. Seeing someone actually turning the idea into something passable is definitely a joy.
Houston, we have got a problem. In my browser at least I think some parts of the screen got cut.
Gameplay wise... the difficulty curve is kind of... LOL. I don't know how the spawn frequency increases with time, but at 5000pts the summoning rate jumped so quickly.
Art-wise... at least this doesn't suffer from inconsistent pixel sizes like some of the games so far but... did you stretch the cloud or something? Some pixels look stretched there.
P.S. the music definitely fits the game.
