I'm planning on creating a YouTube Tutorial on how I made this top down scrolling game (So watch out for that!). I picked a simple concept and was playing around with different ways of using broadcasts in game loops. Press any key to start, then WASD or Pointer Keys to move - Avoid the red zombie squares, and try to reach the green checkpoint - and finally the green exit! Word of warning... IT'S DIFFICULT!!!
@griffpatch made this FULL credit to him. I just made it (W A S D) applicable! :D
