I experienced the same strange clipping others had problems with. I picked up a staff and then went zooming across the world! Ignoring the collision interactions, I think the environment set up is really cool. I'm digging the psychedelic wizard tower. I think players would have greatly benefited having a little more guidance. It's kind of hard to tell what you should do in the tower. It's a great start and it just needs some signs telling players what to do. Great work!
