Great game! My top pick for the jam. I had fun figuring out the building logic of the pipes. I wish I'd been able to play it on stream. If you can get the pck file added I can show it off on stream later and praise what you did.
The trick for deleting: you have not be placing an item. So if you're placing pipes, you have to click pipes again to deselect and then the right click works. An easy fix on the button logic so you can right click to remove at anytime.
