Thank you for playing and your video!
I just watched your video and yes, you managed to break the game. Sorry about that.
You are actually the first one to fall into the void. The funny part is, that in the very recent version, I did actually address the possibility that this scenario could occur. Therefore I added an invisible floor in the void to kill the player from fall damage.
After watching your video, I did some testing, and the same issue occurred to me as well. It’s because you are crouching close to the walls. It happens when you release the crouch button, then the player collider gets pressed through the wall somehow. I’m considering disabling the crouch function for now, because it doesn't do anything special to the game anyway.
There’s definitely more content within the game for you to explore. You were far from done with the game.
Too bad this issue stopped you from going again, but I understand.
I really hope to see more from you.
Cheers
