There is a known bug in the newest version where your mouse locks up after a win or a death.  As a work around until the next patch, Press Ctrl+Shift+Esc to open the task manager and the mouse sometimes unlocks itself.  Otherwise, just kill the game in  Task Manager.  This will be fixed on the next patch.  Thanks for playing!  Please give me a rate and some more feedback, you guys are great.  Also, check out the discord channel(link in the game description).
