I think its a solid game.
The concept was very cool and I loved the pickups you sould get. It got pretty hard though, I couldent beat it. I think it would have been a bit better if the early temples had more places tat you could go back to later with new powers. The only real gripe I had was that I was unable to jump while I was holding the arrow keys. It made the whole control scheme feel clunky. Just touch up that code and this will be great.
