Meh.
All you could do was decide where to go, and you couldn't even do THAT right!
When you go right to jump out the window you die. But if you open the door first, instead there's a portal. Very confusing. Also, it glitched out on me and now im stuck after pulling a second lever. I thought it would get more interesting by maybe having a play on dimensions as maybe going through the portal again would cause the door to appear. But, of course you can't go back through the portal, so now I'm stuck.
Try harder next time.
