I liked the mechanic here a lot and it was fun to play as it is - though I think there's a lot of things that might be improved. Particularly, I think it would be nice if either the ship moved much faster (to make a game of more skill) or if there was some more long range visibility or a map (to allow more puzzling) - and I think this could expand nicely into either direction. I also wonder if there could be more variety - maybe, for instance, there could be obstacles that would dissolve if hit by a hook (or could only be hooked once); I'm sure there are other ideas, but more variety would improve the game. As it stands, it's a good short experience, and the graphics seem fairly polished and fun.
Also: I didn't like the keyboard layout for restarting - sometimes I would fly off towards a thingy by accident, and would have wished to restart from the last orb immediately - but this not an option. Also, since "R" is so common for "restart the last level", I pressed it twice wanting to go to the last orb, but instead going to the start, which was sad (especially since I did it both times at what turned out to be the second to last orb!)
