That's a real "dark" game, lol. Think it fits perfectly for the theme.
At the first run i just tried to use the gun fire as flashlight from time to time. Saw that in your trailer, and think that's actually what we are supposed to do and what's a pretty clever game-mechanic. But not sure if it's a bug or intended, but the magazine which i took from behind my ears always had as much bullets as the one inside the gun. So, as soon as it reached 0 also the new magazines had no shots anymore...
So on the second run, tried to remember the way and after some time walking around nearly completely in the dark and a bit disoriented(i did not really see the blood in that darkness tbh^^), found the switch. That was actually pretty cool then, to discover what you before just could have imagined.
But somehow did not found these 2 blue heads... or at least they seemed not really "blue" after turning the lights on, so not sure, if i really have completed it yet?
All in all a very good looking (as soon as turned lights on), fun and somehow spooky experience. Great job for your first VR game :-)
