Unique idea. It was unclear what to do at first and I just kept dying for no reason 5 or 6 times until I accidentally pressed spacebar and found out you could switch modes to illuminate the path. After a few more attempts, the pathfinding became too consistent where the energy wasn't even an issue because I could just illuminate the initial direction/distance and then just staircase my way to the goal. But, those are pretty easy problems to solve for, and there's an interesting core there that I could see being expanded into something bigger. Good stuff.
