Wow, good amount of polish on this one, real nice job! Really like the introduction and the soundscape. Lighting was also a nice touch!
Couple of improvement directions:
- There's no indication of why would you pick a door over another. More incentive would be nice.
- Felt really annoying to have such a long reload time when you do single click fire rather than automatic shooting. Cater to those who don't like just holding the trigger please!
