I like the idea and it fits the theme.
My biggest pain point was the controls. Some of the platforming sections were just too hard. I get it, you don’t want to make something so simple that you can beat everything first time in 5 secs, but some of the jumps were just requiring too much precision. It’s especially hard with an FPS controller.
Another small thing is the length of the corridor. Because you’ll have to go through each level, it would be nice to have smaller corridors. That way, we don’t need to run a marathon playing the game ^^
Congrats for your submission!
