Sorry to hear you couldn't finish it man, that bug I only figured out after the jam, I certainly never intended to make the "game" unbeatable. I'll try to put out a patch (if that's allowed for the jam) if I get time, my new job I started has a 9/80 schedule so my evenings have been thin on time.
I haven't encountered the chaingun ammo disappearing or issues with the restart button before so I'll look into those as well, if you have any more details on those two it would be much appreciated.
In any case I'm happy you and everyone else so far has loved the intro as much as I have, thanks man!
