I thought this was a fairly playable game for what it is. It's just that I usually play games that are better detailed than this. It wasn't terrible, it was just lacking in terms of gameplay. Then again, it seems like you were trying to create a simple game and in that sense you succeeded. At least you're working with diamonds, which always make something more appealing. There isn't a lot of sound, but there doesn't need to be.
This is one of those games where you really make your own fun. You have to just think of clever combos to make to entertain yourself. It's fairly easy to learn how to properly launch something at the right speed. I guess it is a fairly original idea. The graphics, for what there are, are decent. It's a fairly fine little game.
