Thanks a ton for playing!
hmmm, you're the second person who has mentioned drifting. I have been unable to reproduce the issue. Can you say more about what happens?
I noticed these steps in order to get this bug:
1. In First Person phase, move the mouse slightly
2. Then stop the movement with the mouse
3. Notice that the view moves itself on the right
5/5 on my side
Moreover, I noted that the bug stopped if I moved again the mouse but faster on the left, then stopped the movement -> The bug disappeared.
No problem! It might be specific to the equipment, which is quite hard to fix properly unfortunately.
However, it reminded me a bug, that I had a long time ago, where the values from camera movement input weren't properly reset after stopping using it. I shared to you this information just in case, it might help you.
