Awesome game. Really good implementation of that "fake block" idea. A lot of different cool gameplay situations and mechanics. Few flaws here and there, just for your future games: Height of spikes and height of blocks are equal, so I had some weird behaivior when I land on block from my right side and on spike from the left and take damage. Also, few level sections felt a bit random. Graphics look awesome, good sprite quality and especially light. Audio was good, but you should add a slider. Despite all that I loved the game and completed it. Good job! :)
