Great game dude, the design is amazing (loved the nipples) and the puzzles got smart and challenging pretty fast. The only thing I had problems with was depth perception, maybe distinguishing in some way the top of one block from the side of the ones behind it would help with that. Something like a gradient shadow down the side of the blocks.. but I really am nitpicking at this point, this is truly a great entry. 5/5 design.
