Very good game! The following of difficult levels with simple ones was an appreciated implementation, but I noticed inconsistencies with the hit detection. By level 20 it becomes customary to check anew how the blocks interact in order to gauge how to complete the level, and this proves especially cumbersome with the <> shaped blocks because often the top end will react much sooner than the bottom end. At level 33, which required you to destroy single tucked away objective blocks using hitboxes in the same orientation, I called it quits, but until then, not a bad game!
