For 16 hours this isn't bad. There's a nice variety of levels, decent art, and even an amusing backstory. You got a giggle out of me with the ship flying-off animation at the start. The game itself feels a bit...hard to control, in a bad sense. It was very difficult to predict my trajectory even vaguely, and you were asking the player to hit very small targets. I think a lot of the problem came down to the ship not rotating at all. It was difficult to tell which direction I'd be accelerating in. Some particle effects from behind might help for the same reason. There's probably also something you could do with the physics but I suck at movement so I can't help there. I wouldn't say the game feels bad, especially given the time constraint. But it doesn't feel as smooth as I've grown to expect from space/gravity games.

P.S. - if you replace your dropbox link's "www" with "dl" you'll skip dropbox's gui

Thanks for the feedback, yeah the trajectory is a little hard to see I agree. I added a motion blur to try to help but it would seem it is too subtle.I was experimenting with different control systems (can be found in source) but didn't include any in the release. I agree that I should have used some particle effects, might add them as an update if others have this problem.

Have a swell day.
