You did a good job. I really enjoyed the atmosphere in the game, and the sounds fit and brought things together. One annoying thing was when the lights spawned outside the wall, so you could see the light coming from the wall and know there was one there but couldn't get to it as there is a wall. One thing I found funny was not going down the hole and jumping off the outside of the top so you could fall looking in from the outside. The controls were fine, and it was nice that I could look them up in the game, but it also looked like there were controls that were not in the game, making things confusing.
Overall, you did a good job making it, and at the start, it was fun jumping around to get the lights, but it got very repetitive, and with it not having any change in difficulty over time, the fun just slowly faded away. You need something that can keep you on your toes and not just repeating the same things. Grinding things in games by repeating the same thing can work, but not if that is the only thing. There needs to be something that can change that grand up every now and then so you feel engaged.
