thanks for the feedback on the respawn/controls front. I never had this issue in playtesting myself, and I tried to break it in many ways :D.
What browser were you using please? I'm having trouble replicating some of these player input bugs. Think it's a weird combo of the new system, WebGL, and browsers.
The zombie jump bug/feature was left in intentially, as i thought it add a bit more fun to be able to scamper up a wall at times :P,.. but I need to pin it down a bit more rather then leave it buggy :). Maybe sort out the coyette jump instead as somone else sugested.
I had forgot about physics materials for surfaces though :D, so thanks for the reminder!
Thanks for playing! I apreciate it!
