Davy Lamp Puzzle proof of concept. The intention is for the lamp to be dragged around the screen to find oxygen levels of different paths. Currently requires Davy Lamp to be clicked after dragging to update Could be used to find a "correct" route with high oxygen levels, find our way to a lower oxygen area (finding/saving people or maybe find out the cause), or to solve a problem (eg caved in and use the lamp to find gaps in the rocks)
