first of all, thank you for playing my game! it is great seeing my product being out there.
In order to make the surroundings brighter you might consider pressing the L key to activate the light. In order to move faster you may consider keep pressing the space key as well. I will try to add more settings in my future releases, things like mouse sensitivity or gamma. If you have trouble finding the right roots, you might wanna check a map I've released a while back.
It was a conscious decision I made to make the game have a slower pace and have a darker ambient. I believe this gave the game a cinematic look. But I might've been wrong?
Anyway, thanks again for playing my game! Wishing you awesome holidays!
