This is a good idea for a game but is it just me or is this game moving too fast? I got dizzy playing it and couldn't follow much on what was happening on the screen. I am 28 years old, so I guess my gamer reflexes are pretty bad but still I found it difficult to play. Most of the time I could not react to the bolder spawning. Maybe it is the background graphics. If you make them stand-out less it would help.
