This is a very good example of how awesome games can be made from a simple game mechanic. I've never imagined I could play a trash-collecting game for such a long time before I played this game. Also, the artwork, music, and SFX is superb and creates an engaging and immersive space atmosphere which I like a lot. The controls are brutally difficult to master, making it impossible to do some precise movement, but I like this because this is how collecting junk in space should be like.
I don't know if you intended to make it so, but I noticed that when bad junk hits a good junk or another bad junk, it becomes good junk. So I figured it out that the better strategy is to wait for the bad junk to hit others and then collect it, instead of using the ship's repulsor field to do so. Still, collecting bad junk is extremely dangerous since it's very heavy to catch, but somehow I love this helpless feeling when your ship got dragged by the heavy trash to the edge of the screen. Anyway, Nice work!
Overall, this is a very well-polished little game. I enjoyed it a lot.
