Maybe a candidate for aGTW:
Joy was the inofficial winner of a programmer competition for the German mag "ASM - Aktueller Software Markt". This competition ended undissolved for some reason ( i.e. some editors left the ASM).
It was planned as a shareware game then, a few years later a commercial release seemed to be possible. A small software house promised to publish the game, but they couldn't come to an agreement and the game wasn't released.
Anyway, the game is written in AMOS Basic. It looks nice enough, but only in German language. Get the full game here:
