This we cool, the platforms you could sink through gave me oldschool platformer vibes, and at first I thought clipping into the wall was a collision oversight, but then realized it was an intended mechanic, which I really like as it gives more than one way to approach each obstacle. I think my only gripe was that I didn't know I could run for a while since there is no in game indication, which led to spikes being a wall that you had to go under rather than over, but that aside, cool game!
