Not bad. The controls are a little clunky, but once you get used to stabilizing with the space bar it becomes rather enjoyable. It gets you to concentrate and to not be too hasty, I like that.

However it is a little short but you did mention that you planned to add more levels. I would suggest more obstacle blocks (e.g a block that you bounce off when collided with) and more themes. the whole red block with blue backgrounds can get a little dull after a while. also some change in music for the themes would be nice.

Like I said not bad!

this game is fun but its way to hard to control

This is the kind of game where you want to smash the screen in frustration. It is too hard. :(
However the music and the animation is good.

not too great, controls were incredibly difficult.

A good addictive game, needs a little more interactive blocks in it, but otherwise its a very fun game, so to the respective reader, if you have time to kill I suggest you play this, VERY fun
