If anyone experiences a bug where you have to double press/tap the arrow keys to move, it is because of a memory leak of some kind. So don’t worry. Hopefully, thats fixed before the Steam release.

Reboot is an old outdated term us old folk like to use that means restart 
My parents said that it would delete all my PC data… -.-
Okay. I will try that.
