Really weird, but as I said I couldn't replicate it. It's good that you specified it was the collision and not the actual warping between rooms that did it, as that's another potential can of worms. I'll have to chalk it up to how I handled Unity's collision (or maybe the collision system itself, I dunno?). If more people mention it in the future, I'll go back and at the very least make some kind of workaround.
I wouldn't mind nitpicks, to be honest. This project was done mostly so that I could learn more about making a game after all. While I wouldn't be surprised if people have already mentioned them, it's still good to listen and for me to think about it for the next time I take a shot at this specific genre.
