See, everything is divided to puzzles with an incremented difficulty. Starting with very simple Box-Goes-Here puzzles, and working it's way to Fling-Yourself-across-this-giant-assed-gap-while-holding-down-5-buttons type puzzles, all with a large body of water slowly rising over the map.
What I want to do, since it's so hard to see where the water is, have warning lights in the corner of each room, like 3 normal lights that go off as the water comes up and then a big red siren-light thing that lights up when you're about to die. I have no idea how to do this, though. Any suggestions?
