The game is fun, but I have some suggestions! I would love to see some more levels, or puzzle elements, but I understand that you didn't get the chance! I would also suggest ensuring that the light always starts in the same position on the 2nd level, because otherwise the player can start taking damage immediately after entering! One other suggestion I have, which is a very small one, is just to add a countdown on level entry, so that the player is ready to start! I wouldn't say it's as important as the other suggestions I have, but still worth considering. Other than that, good job!
