Heya Pikiboiii! First and foremost - your presentation is just *chef's kiss*. Perfect 10/10. The page, the intro, the mood - nothing to add :D
Unfortunately I got stuck here and I can't do anything. The player doesn't react on A or D and I can't interact with the light.

I've tried reloading but I end up with the same problem. Could you tell me what I'm doing wrong?
