FANTASTIC. Best game I've seen so far in the jam. The sprite art is sublime (is there some tweening done with AI?) Controls are tight.
But man it is SOOOOO PUNISHING with really little room for error. And the levels kind of go on for a while although each level displays a very different idea. At least a restart is quick and not too far away.
Made it to the end though (that last bit is just - omg plz kill me already)
I'd say there's some minor stuttering at parts which really kill the game, otherwise, no gripes.
