Those sound effects dude haha, well done. It's a good entry. I would have enjoyed a little music in the background but that's fine.
Despite this, the sprint is waaaaaay to fast in my opinion, and the jump super floaty. It's kinda hard to tell if you hit something or not if you're not listening to the sound effects.
The first room was a bit hard to leave because I didn't think there was something to hit on the roof, maybe put a lil indication so the player will check that :)
