This game is fantastic. I really enjoyed it. It took me a few tries to win but the experience only lasted around 15 minutes total. So a bit short and easy, but fun.
To win all I did was buy a few koalas and komodo dragons and waited until earth made one orbit around me and sold them at a huge profit. A few complaints is that the game doesn't really explain anything to you, so my first tries playing it were basically trial and error. Stumbling across Earth by coincidence and saw the menu pop up I figured out that I was supposed to be trading stuff. Then my ship had trouble moving and I got thrown out of the solar system. I didn't know that adding so much weight to my ship would cause it to perform so poorly. Who knew a few koalas and a couple of bottles of wine could make my ship utterly impossible to control???
The shelf life wasn't explained in the game either, which I figured that out just by trial and error as well.
A readme would have solved these complaints and I would have spent more time enjoying the game rather than fiddling around trying to figure out what's what. But then again, it was only a few tries before I figured it out on my own and it didn't really hurt the overall experience.
(tip to anyone playing: press alt+enter to force the game into fullscreen)
also you should make a web build for the game, since it's not that large anyway. it's a lot more accessible and more people will be apt to play it. just a thought.
