Not bad!
Pretty well done. the one thing I couldn't get over was I felt the gravitational pulls needed a larger falloff region. I would shoot off past a planet thinking I could swing around and land on the next one, only to drift off into space. And for the most part, getting close enough to be effected by the pull only meant sling-shotting all the way around or landing on the planet.
I've forgotten where I was going with this...
was mostly fun.
