It is very difficult, I think it needs some kind of other mechanic to make it more playable. No idea what, so I don't blame you

Fun idea though, and it is fun to play for a bit

I was really hard to do, but I got a loop.  Not much seemed to happen after that though.  The game kinda just stopped.  I think the number of pipe variations is what makes looping the pipe so hard.

Overall its a cool idea.

Cute idea, but I couldn't manage a single loop
