8/10 I love the core idea of the game, although those kill areas are bugged for webGL they look very weird and help make it look like a place you wouldn't want to fall down. Got lost of my first go but now that I see where you have to go it's very fun trying to get a faster time!
Optimization is something I'd like to see a bit of and I think making it easier to wallrun would be a nice change, other then that I think this has a lot of potential.
