Previous demo had similiar problems with clipping so intelligently I made all floors flat and thin, and enemies can't get stuck in weirdly shaped level. I hae to add collisions on top of the Dirk's head.
Music shouldn't loop. I mean, it's a pretty slow and uncanny track, listening it more than a handful of times would be grating. I was fighting with myself if I even should add it. One track without a loop seemed like a sensible compromise to me.
And what's wrong with shift? I'm more of a jump on 'z' kinda guy myself, but having all three buttons pretty important I didn't think that either 'zxc' or 'azx' would be comfortable. Shift is pretty long! It fits perfectly for a ring finger! Would it be better to have it used for interactions or attacks? I don't think so.
