Straight up, this is the best game of the jam I have played so far. The controls and concept are simple, but switching the blocks and looping from top to bottom of the screen allows for lots of complex puzzling. The art is terrific; the amount of character you manage to get out of such tiny sprites is incredible (I particularly love the death animation). There were some minor bugs (saw an enemy clip through a block and generally though the collision shapes could be a bit peak sometimes) but these didn't hamper my fun all that much because the difficulty to finish the game was really low. Making the difficult part of the game the optional aim to score highly was a great idea to allow players with differing levels of patience to finish your game. All in all, very satisfying and fun. I expect to see you with a prize at the end of all this :)
