After 4 days, Google Play has reviewed and accepted Tubes And Fountains. 👍

My fear is about the small display size: the game has very thin clicking points. If the player haven't already tested the game in web browser or locally, it will be kinda frustrating make the right taps. I provided a tutorial on level 1; I hope it's enough.

Maybe the game needs of a virtual camera man that enlarge the points where a click is desired. It's not so easy to do, anyway. The risk is that the player wants to open a pipe tap and the cameraman shoots at another pipe tap.
