Not too bad. Could use less annoying sounds and maybe a scoring system just for shits and giggles and maybe some quick instructions for those who are a bit slower on the uptake. Other than that though I liked the simplicity.
not bad for a time waster but for the love of god add a volume or mute option for he music and sound!
A good attempt
Good concept, but the music and sound effects are really annoying. I would suggest replacing the sound of turning the pipes with something more subtle, and adding a mute option for the sound.
Besides that, you could enhance the graphic environment of the game with simple tricks, such as slightly changing the color of the tubes at each level, adding some small background effects, and so on.
This is a good logic game; by making small changes you can turn this into a very good game.
