A good revision of the classic pipes games with a twist: multiple pipes rotating at the same time.
I couldn´t get past the 2nd level, but it was a nice game. What I found a little bit frustrating is that I couldn't know which pipes will be rotated when I click. Maybe you could add some form of highlighting that is applied to the pipes, depending on the mouse position. I think that could improve the 'planning' phase, which is something I think enhances the experience you want the player to have.
Music was nice, nothing too fast-paced and fits the gameplay.
Good job!
