Nice mechanics. I had a lot of fun slingshoting around and getting into the far distance. At some Point I think i got abroad, there were no Planets anymore and I was just flying along, enjoying the darkness around me. At some point the screen became reddish. I thought i was nearing the sund or a star, but i guess it was just fuel getting empty. Even when fuel was point i was stillable to fire the rocket. If i didn´t close the game, I think the spaceship would still fly through the dark, with the Oxygen-number decreasing far more in the negative (-101 and going). I liked the realness of the Game, even though i think at some Point the operator runs out of Oxygen itself. To space and beyond. Peace, Love and Harmony :D
