This game makes me want to puke on an astronomer's crotch. It is so frustrating with the glitchy physics, random gravitational pull relating not at all to mass of the planets and no restart button.
I had alot of fun on this game. I suggest you create a Steam to-be release with many many more levels, level editor and cost money. I would buy this in an instant.
This game is godawfully horrible, to be honest. The movement is smooth, but the money gain is slow and it's near impossible to kill anything before you're easily overwhelmed.
I have to say, this was a pretty bad game. Just in my opinion of course, but World Dominator was much better. All the memes and other crap in this game just make it.. much less fun.
