I like the game concept. I didn't read the author comments at first, so in the beginning I had no idea I was playing against other people, as soon as I figured that out, the game became more interesting.
Playing against other people is a really nice idea, though it would be nicer if you could play against other people in real-time. Like pirateplatypus said, I too, kicked the crap out of me.
And I think it would be nice if the graphics got a update.
All with all, it's nice game.

The game okay, I think the graphics need updated, the shapes make the game a "turn off". Maybe some real looking Gems?

This is a really fun twist on the genre. Though it does lose a bit of the excitement when you realize that you aren't playing against other people in real-time. I figured this out because I played a really good round. The next round I got the crap kicked out of me, by myself.
