About Portal Puzzle

Portal Puzzle was created as a project for the Flutter Puzzle Hack. The classic 15 slide puzzle is fun until you figure out (or see on internet) how to easily solve it every time. When I had a chance to create the puzzle in the digital form, I thought: why not do something which is not a strict copy of the "analog" box with tiles. Why not allow those tiles to move through "portals"... The rest is history (git log).
