I wish there was an impossible badge for this, there is nothing in this game I can't do by now. Playing it is like meditation for me, I can do it while my mind wanders elsewhere. Great game :)
What intrigues me the most with games like this (it's a bit similar to Dolphin Olympics 2) is to find out what bonuses are in the sky (moon, saturn and etc). How many of these are there? I reached the satellite (or whatever that was) is there anything exciting beyond it?
The basics are good. Fun to play. However, reupload without the changing colors and add a mute button (maybe even change music) and this game could be something. I would rate it 5 if it were not so annoying. I won't rate at all at the moment.
I enjoyed it. My only complaint, like many other kongregaters, is that it's a bit short. However, the difficulty level does not bother me at all. I enjoy playing games that are easy sometimes.
Updated. Sorry for that.
