This is a weird little game; I played it long ago, elsewhere.
It's a very bare-bones space trading sim, and a very, very easy one at that (eg there's no cost penalty for buyback/sellback of goods, and there're random goods lying around the starports you explore). It is, weirdly, entirely on foot (no space sim stuff at all- you essentially teleport between ports), and the game features regular FPS levels, where you're basically clearing out a deathmatch arena filled with simple bots.
It feels like- and I think it may have been- a student project, originally. It's like a proof of concept for a space trading game. Everything feels kind of half-implemented, and there's a goofy sense of self-deprecating humor throughout. The game doesn't really end so much as it stops going. It's weird that it is still being sold for money.
