Happy to be the 20th person to rate your game! :)
The gameplay was simple but fun and you managed to use the basic shapes well. Extra points for the option to adjust mouse sensitivity, that issue seems to come up a lot with first-person games.
As for the typing effect on the texts, I would recommend adding an option so when it's typing and you press E you don't skip the dialogue but the typing effect for that part. I like to read all of them, but usually just press E/space/click to skip to the point where I can see all of it.
Also, at some point I fell through the game floor, is that part of the design or a bug?
