Yeah the wood blocks were not supposed to be rendering on top of things, and they were supposed to be breakable. They were mainly just for show as they break immediately and don't actually hinder anything.. Hmm, maybe the shurikens would be blocked by wood but the spike goes straight through it, that would be neat.
Also really sorry about escape key, I needed to implement a way to go back to main menu and just re-used the death screen :(
Glad you enjoyed it over-all, and the wall-surf ceiling-hop was not intended really, but maybe now I'll consider implementing something like it, or even an upgrade that let's you do that kind of surfing.
