Hey Super Jesus, thank you for the kind words!
We just ran out of time for nice puzzle/level design unfortunately, but we're keen to release an updated version to address small bugs and provide better level layout.
Regarding light, we decided not to add health so the focus stays on the light puzzles. As such any time you enter a lit area a countdown begins, if you're still in light when it hits 0 you're toast :D. I think it's set to 0.6sec in this particular build. Also, the blinky light coming from inside the house is bugged and won't hurt you, but don't tell that to anybody O_O
