Very clever, very twisted and very fun. There was definitely a 'portal' vibe going on with the test subject talk and the slightly off-kilter machine. Too bad we never did escape or find out who we were.
I do wish I had read the summary about the arrow key business ahead of time though, I almost drove myself nuts on the logic problem proving Micheal Atkinson is a douche because I couldn't see half the answers. Is there any way to make that more obvious, or add it into the game/menu screen just as a heads-up to players?
