When seeing the theme unstable one of my early thoughts was something like this, intentional bugs as a main mechanic, but wasn't sure how to explore that idea. I like the approach you took here with a portal-esque test facility, and the use of voice over. I thought the most clever bit was when you had to climb the tall wall with the box, I had seen enough glitch videos to know what to do and it felt fun knowing that. I didn't quite reach the trophy, 'crash'd just before it, alas. 

One note is be careful with inverting mouse look in an fps game, you did have the VO line realizing that but yeah. I'm notably susceptible to motion sickness and it did set it off, had to lie down for about 30 minutes for nausea. I don't blame you it's hard to know if it doesn't happen to you, but good to be aware of that when suddenly moving an FPS camera in way the player can't anticipate.    

Very interesting game was interactive and fun. Having a narrator in the game was cool, overall, I had a great experience. I would rate it if i could.
