First thing I did is ran through door behind me and fell through the level. Then I did the same with second door in front of me. I was running around, sometimes through objects and walls... if they were illusionary walls - they looked glitchy. I couldn't pick up objects or use anything that I ran across.. You can go inside the table and it will be huge for some reason.
It looks promising, but sadly is unplayable at this moment :(
