the game looks great. I dig the plane particles on the ground.
To me the gameplay felt a little boring, as you had little control over what comes up next, so the best choice often comes down to just luck instead of user input. Eg every level you're sitting their at the end with the correct multiplier and have to wait for the correct shape to show up and just tank damage until you've got the combination right.
The real killer is the music though. I really like the soundtrack - it's great.
