Nice game! At first I was thinking there must be hundreds of ways to connect these, and then I realized how few there were.
A few things: I found the font hard to read due to its small size. I also wasn't sure where to click in story mode and kept exiting to the main menu. It would also be nice if right click spun the tile in the opposite direction rather than undoing. Faster tiles spins would be nice too. Other than that, fantastic game!
