Hey, thanks for your feedback, I do appreciate it.
Yes it still has some weird glitches where stuff flies off..
FYI, Junk velocity is limited to 1000px/s and the planets are the only gravitational objects, so your Junk will return.. eventually.. :-)
Nobody can say when though..
Thanks for trying. If you ever try it with a friend, please update me on coop gameplay.. that would be awesome!
