bubble cat

　　welcome back, bubble cat. we have another situation, and this time you've only got 60 seconds

> how to play:

arrow keys: moveX/Z: continue to next levelctrl-r: restartctrl-m: mute you don't have to full-clear every level -- skipping a level without clearing it just gives you a points penalty (-5 per remaining bubble)

> code:

this game was made to fit inside two tweets; i.e. <560 characters of code. here's the full game, in 552 characters: (and no external sprites/sounds)
