Classic game

Not a bad start for a puzzle game, but there are a few problems with it, such as the delay when you click on a matching pair or, as @DarkNote said, blocks not getting drawn into the middle when row is gone.

Reminds me of a lot of apps that try and get you to pay to beat levels that are just chance.

Nice try :P

Eh.... that wasn't an insult.
I'm not much of a programmer, but there could be a few improvements on this one. Frist, the sound was just plain annoying >< You could add a little more thought to it, like timing the game. Also, when you delete blocks, and a few are isolated on the side, those could be pulled over to the main body of blocks (get what I'm saying...?) to make it easier. I suck at these "remove the blocks" games, including Tetris, but... eh.... this one wasn't that good. 4/10, and 2/5. ^^; The blocks could've been bigger, too...
Or, if you had levels, it would've been more interesting. Like 1st level, 2 colors, 2nd level, 3 colors, etc... :P

WTF?!?!?!

Biggest piece of crap iv ever seen, it need 100% improving and 100% attention on improving, or did you make this game to realy make it as crap as possible?!?!?!?

Needs some SERIOUS work

you could make a very cool fun game out of this but instead you decided to create a very short and cheap game :\
