Fantastic little game! Although I noticed a couple of things:
- For browser games, Ctrl+D is bookmark in lots of web browsers. So when trying to crouch and move left you end up bookmarking the screen a lot.
- I left the green orb for the final orb and I think the fire bit made that level impossible with only the green orb.
I love the idea of losing abilities as you progress instead of gaining them and overall it was fun. Great job!
