Geez! The art, sfx, and music are stellar. Being able to squeeze in that many puzzles in just the week jam is also extremely impressive! The game runs very smooth, no bugs that I noticed. I really can't think of any critique other than maybe that the snowman enemy's hitboxes were not super reflected by their sprite size, but you may have done that for balance purposes. It did add the appropriate amount of difficulty.
Great, great entry!!
