Fun one! I didn't see the control scheme written out so I immediately destroyed my red block and had to figure out what was going on by myself and had a big OH NO moment when I realised what, exactly, should not be fed.
Clear graphics with concise, condensed mechanics. Just the right amount of "length" for a single level, could be infinitely varied by white cube placement/time constraints/speed for varied levels. The sphere grows a bit unevenly, the top portion hits the ceiling before it hits the ground, so that should probably be centered properly in a fix, if you update the game.
This thing's got promise! One of my faves this jam
