Try to beat the level I created :): https://drive.google.com/open?id=1iow7y-KyfNB5Bnm9xrZ4tZvmE3-fVpRL
Great level creator! Matches the theme 100%. I like how the blocks merge perfectly if you put them together. The menus and the font is good. I'd love to have some kind of trap (trapdoors, spikes, fire) to make it more challenging. A fullscreen support would be nice, since the game-window is too small on full hd displays.
The only thing that bothered me was the size of the character. It seemed like a 1-blockish-width/height dude but he needs two blocks and cant fall through a single missing tile.
Minor bug: I couldn't use the letter "Z" (for "MAZE") in the save game.
