i dont really feel like im playing a game when mousing over the entire screen of indiscribeable objects does whatever it wants and i win. maybe if there was a bit of color i may be able to tell what the objects are and be able to think about my next move. or maybe even i would have to click on stuff so it would at least be a point and click game. nice atmosphere but bad exicution.
how does flipping the same 2-way switch down, up and back down again change the portal 3 times? maybe you should have 3-way switches or multiple switches for this to make sense...but besides that, the game is good.
