Nice take on a classic. I like the look of the isometric maps and I wasn't to bothered by the leaves and snowflakes, could be tweaked but I think the effect itself adds to the vibe. Nice music as well. One thing I did notice is that if I held W and and a direction and then pressed the other direction while up against 2 blocks I could clip diagonally between two blocks I didn't use it to solve the puzzles though :D
