Really good game! I love the artwork, the low poly style is well met. I feel like this game would have benefited greatly from having a grid type system for inserting the mirrors. I found it a little awkward to try to get the right places to place them, maybe this is on purpose to add difficulty but I would have gone the "casual and satisfying puzzle game" route in terms of difficulty as it adapts more to the style of your game imo. I can't stress enough how awesome I think the overall aesthetic is. Good job!
