I tried to use this to generate Numberlink puzzles. As the input I gave a solved image from https://github.com/thomasahle/numberlink https://github.com/thomasahle/numberlink . However I never even got to the "progress screen" / "cells collapsed" count. I guess the input image has to be very small for this to work well. I also tried generating some large images (like 1000x1000 pixels output, but small 64x64 input), but it only collapses around 100 cells/second, so this still takes about 3 hours assuming no contradictions are encountered. Works well for small inputs and outputs though!
