I'm not sure, you would have to describe your issue in more detail. The full game is included, unless there is some sort of bug I didn't catch.
Well when I launch it, it just starts me in the bed room (no title screen, phone ringing, TV playing). I can gather the mask and gun and get in the truck. After taking the 3 bodies from the campgrounds and putting them in the hole, the All Done text appears and the game quits.
AHHH That's the alpha version :d
It must have been accidentally included over the final version somehow. I will upload a fix right away. Thanks for letting me know.
