Good game, maybe the game should have a different number to add to for each level? Start from smaller panels and as the game progresses add more columns and the bricks move down faster? Or have a speed trial mode to test your math skills (which would work great if you were to add to different numbers other than 10) Achievements? And.. A cute kitty face that, depending on how your doing, changes expression, again to how well or bad you are playing the round, such as frowns when the bricks get to high, or a happy face when you start speeding up with taking away bricks? just thought it would make the game more lively to have a cute animated kitten to watch you play =D (+)
