Oh, thanks for the feedback! If you have a problem with the infinitely moving cursor, it's a browser problem, especially if I know Firefox and Edge have that problem. I can only advise you to try running the game in a different browser, it's a unity problem, not ours :c
The cursor is not moving infinitely but when I moved my mouse right the camera rotates to left and when I moved my mouse left the camera rotates to right. But I tried once more and in was good so it could be bug on my side.
