To pause without restarting: Press P to pause, then again to Un-Pause.
Up this comment so people know how to pause.
In case other comments get bumped down: Menu is not Pause.
I just realized the never actually said how to pause.
The P button pauses the game.
+ this post if you think it should be put in the instructions, or at least be seen.
My biggest concern:I can't get my mouse cursor back after clicking on the game screen, can you add a button to bring it up?
Solution for others with this problem:Ctrl+Alt+Del,then cancel.
