You could have done better
Ok here are your faults and problems with the game:
1:There was no point to the game.
2:The story made no sense.
3:It was too easy.
4:There didnt seem to be much effort put into the game.
5:The graphics were poor and shoddy.
You should try to improve on the above and maybe add a system where you unlock things or get some sort of upgrades, also the style wasnt original, it was the same as the catch the good and leave the bad things sort of game and there are too many of those games around that it gets old and boring.
Try to invent a new type of game that nobody has made before and try to make it a decent game, think about whether its worth playing before you release a game, and get some quality releases, maybe then you will get near the top 10.
