This game, at it's core, is a solid platformer. There was good level structure and movement variety. The game could be improved by fine tuning the collision and player movement. It felt really finicky, especially wall jumping and walking on ice. The ice would launch me in one direction or another incredibly fast. The game could also use more checkpoints or better hit detection for the spikes. I died on them enough that it became unfun replaying areas. Also, while the sprites themselves look really good, they could be improved by making sure the pixel resolution matches between them all. Some sprites were a much higher resolution than others. Overall, great job establishing atmosphere and game mechanics.
