This game is kept somewhat simple; would be better with pressing keys.

I would recommend some hotkeys for the buttons, and maybe a lower volume or mute button for the audio. I think that maybe a health bar of some sorts would be nice. I do like how the blocks come at varying speeds though.

Interesting idea, but you should improve/add some of this v
A mute button.
The UI

Also, if there are 2 of the same color on the screen, and you hit the colored button, both of them vanish. This bug/glitch/whatever makes the game abit too easy.
