Alot of content with new mechanics being introduced to keep the game exciting. There were a few points where it took me a while to realise that a particular player state or action would react with that obstacle in that way. eg. Pressing sideways again while against the bricks hanging under the conveyor belt in cave 2 or the player still moving against sideways fans when in a non-stretched state. But everything else was easy to make sense of. I like how each obstacle was introduced in a gradual way at the start of each level. Only made it to Ice 2 so far and appreciate the save files. Nice work.
