Overall, a very confusing experience. Presenting a player with controls would be nice.
I could only move in a line (with W and S) on this three-dimensional plane, which was confusing (and maybe a bug?). At one point I discovered that I can pick up stuff with E but I never discovered how to really use this stuff or attack my enemies. Also, there was some number displayed on the screen, not sure what was its purpose. Also, the stuff I was picking up started to cover a lot of my screen at some point. And I also fell through the floor and ended up in the middle of nowhere. See, confusing ;).
Any chance on making a web build? it would probably get a lot more people to play
