Cool puzzle game! Very hard. Got me scratching my head as soon as the second level. Maybe to drastic of a difficulty curve? anyway good job!

I also like the yellow block and the idea of playing on the timing of the block. It really is a great element of puzzle. You should add blocks that disappear every three frames too later (or any other number of frames). Or blocks that disappear and come back later. Or blocks that move to another places. So much potential!
