Great little entry. I was going to say almost exactly what @stuartlangridge said below, so I'll leave it at that. Nice job. I wasn't even bothered by the lack of sound after a while because it almost added to the atmosphere of being alone in some space station/ship. That was killed a bit when I got outside and it appeared I was not in fact in space. So I guess that can be my only real complaint. I found 260 coins. I was shocked to see there were still ~60 left to go. Great job.
EDIT: Oh man, I loved Pixel Peak last year. Glad to see you're back and still doing good work.
