A bit odd of a choice for controls but overall a solid start. Nothing unique though. 

nice game! but the controls feel a bit weird, you could improve it by making a "brush" thats paints the pipes instead of selecting the same pipe over and over.

It’s an alright pipe maze rendition with a couple unique features, but there’s a lot of pipe mazes in the world. Having puzzle elements which rely on physics are a little annoying when the physics aren’t always exactly identical on every attempt - to be clear, this is more a problem with the engine and not so much you, but it is something to be wary of designing your game around.

i really liked that there didnt seem to be a perfect solution to each puzzle, it was really interesting to think about the levels in that light! Nice job :D

It was decent but has some bugs.

A bit buggy. Needs refined mecanics.
