Cursor stuck

[Romulator]

Dunno if this will help, but perhaps lower the resolution of the game to the maximum of your screen, and run the game in Windowed mode? If the game loses focus (like, it is not the active application) it will cause the mouse to be in the top left corner and becomes difficult to move from that spot. I have a similar issue on my Windows Laptop, but I always run the game in full screen, so I would have yet to test it in Windowed.
