Thanks. By jank do you mean framerate glitches or other performance issues? The simulation stopping for the victory screen is my fault, it was set to continue until I decided it should pause, in retrospect it would have been fun if it didn't.
Oh no worries, nothing like glitches or performance issues! Just some things that can be polished, like being able to place pipes in unaligned ways, the button text overflowing, etc.
Very minor stuff, nothing that interferes meaningfully with the gameplay :)
