The music is nice, but that's about the only really good thing. There doesn't feel to be a real objective. I tried several times to figure out what triggers a game over, but I'm still not sure. I let several of the blocks go by, but there's not health counter or anything for if that's what causes you to lose or how many times it has to happen.
Besides that, the game is just... empty. You click blocks to get points. Points give you your score. This feels more like it'd work better as a mobile game where you could compete against friends. More mechanics would benefit you greatly.
