I love the idea of challenge rooms and these faceless thingies getting in my way! I'm not sure if my playthrough was buggy or not, they all spawned in a clump in the middle and moved very slowly outwards. I get the gist of the game, especially combined with the screens provided, I imagine they were supposed to move faster than what I was seeing. I had to run with compatability mode to run it at all.  Maybe there could be an objective in each room that had to be completed before going to the next?
