Short and sweet game. I liked the use of the theme for power in a mine, it was an interesting challenge and I loved how the light looked and how it would get blocked by the walls. The art was also nice and simple which worked well. The only critiques I have are just for some of the hitboxes. It seems the enemies mostly only get hurt if they hit the lights from left or right, but rarely when from up and down. I also could get the player stuck if I place a light in front of a wall. Because placing a light moves me up, so if you just place a light near a wall it pushes you into it. But a solid game, good job!
