I’ve just remembered how to do a glitch which completes the game. I told Schmidtty about it on one of his streams a while back, but i got the details wrong (sorry about that).

I THOUGHT it was just a case of running out of TV fuel and jetting off any planet. Now I remember - it happened when I put a black egg on the little planet in the starting system, THEN running out of fuel in the TV (so the little rescue pod animation happens) and then taking off. The planet explodes, and the ending plays out.

I’m about to fire the emulator up and try it now. Will let you know how it goes
