Can't hate it
This was a fairly mediocre game to play. My main beef was that there was no music and for that matter no sound effects. It just always seems a bit lazy when people do that, not that I am accusing you of anything. The best part about this was the graphics. While there was not much detail, everything in the game did move fairly smoothly and there weren't many problems with the controls. It did get harder as it went on of course.
The thing you could probably work with the most is put in more detail. It does not have any clutterment but there should also be some more things going on. Again, sound is what can really draw a player into a game. I only noticed just now that the things the player is collecting are medals. That is a pretty original idea.
