You could improve the game a lot with some little tweaks:
- add a repeating background texture to support the movement motion of the spaceship
- show the limit of resources your ship can hold
- make the asteroids move around in space
Also there's a lack of challenge at the moment, there are many possibilities to make the game more dfficult and therefore more fun. You should really consider adding some in the future :)

Great idea, but it gets a little boring after a while. Nice job though! Needs some sound!

good idea

nice idea, but have to have more features to make the game interesting like mini map where some asteroids are there, some bg, some challenge like enemies etc..

Cute idea, but there wasn't really enough to keep me playing for long - two things this game could have really used is a background of some sort so that you can see how fast you're moving (at least you had the coordinates, otherwise you wouldn't have been able to tell at all) and some sort of radar or sensor to detect nearby asteroids.

I finished the game, the controls were smooth, but there were not that "diversity" of features in the game.
