Oh wow, I started learning how to make games when I was 15, in GameMaker 7. Would have loved to use Godot back then!
The graphics are nice, I love how you drew the controls on the wall. That lighting is the best most surprising thing about this, it's so good when it passes through and around objects, showing where it's safe or not. It's a little tough to tell when he's coming back but it does make you feel like you have to rush haha.
