Eugh, yeah. I might remove the no walls mod in the final release, because the implementation is most definately not ideal. There's just too many ways it can screw up. For example, if you hang on a walls, try moving around with WASD. You can still move while hanging. Oh, and if your default keys AREN'T WASD for movement, the no-walls won't work for you. So yeah... maybe I'll put it up to a vote later.
