As the first in the series, I thoroughly enjoyed this. This seems like something that would show up in "The Hitchhiker's Guide To The Galaxy". I guess it's just the notion of being around in space. I like how you could adjust your throws. It was pretty hard to beat the level without doing that. These must be some large golf balls.
I think the planets themsleves have less gravity than the black hole! I do appreciate how good the visuals are. The crystals you collect are nice too. You should call this Triple G. I like how the arrows point to the sendoff point.
