Interesting, but the mouse is on the screen the whole time which is extremely distracting. I also "clip" through many of the walls. Another problem is the lack of direction, which I guess serves the purpose of feeling alone and excluded, but makes the experience much less user-friendly.
Assuming that this is a work in progress I think there's potential here. You've got something going on with the aesthetic and I really wanted to keep exploring, but too much was lacking from a technical standpoint. Good luck going forward guys!
