Good game so far, who knows what three ingredients you need to put in the mixer to get rid of the crystals? And what you can do when you open the vent?
Two problems I have with this game: One, the fact that the game often glitches and doesn't allow you to help your companion up. Second, there's at least one door in the game that has the option to open, but doesn't work when you do it. Overall though, good game.
