Really cool idea! I can't think of another game with the mechanics this game has. I will say that I found the controls to be a bit frustrating to work with. For example, sometimes the character would bump into the floor after I tried to walk off of the top of a ladder.
I liked the overall presentation, although I think the spike hazards are a bit visually misleading. Maybe they could have alternated between being all the way up and all the way down instead of moving up and down so that its clearer when you can pass through them?
Good effort ^-^
