Gameplay is on a grid from 5x5 to 12x12 in size. Each level has a number of "depots", from which the player lays section of "pipe" to Von Neumann neighboring tiles. Pipes cannot cross each other, and a tile cannot have more than 1 pipe. Pipes cannot be placed on depots. Click a depot to "activate" it, and then place the pipes from that depot. There are 3 ways of placing pipes - clicking on the adjacent square, dragging through adjacent squares, or clicking several tiles away in a straight line from a placed pipe or activated depot to lay pipe on each tile in the line.

Thanks for giving it a try - I would appreciate any feedback!
