Hey first game? Nice work!
I strongly recommend you go grab an FPS controller from someone like GDQuest or KidsCanCode as that will springboard you into having a worked 3D game in no time and you get stuff like mouse look for "free"
Great effort for a first timer. Throw in a crazy spooky sound or atmosphere track next time maybe
Also, there is NO WAY I'm playing a game like this with the lights off!!!
