Such a great concept, highly addictive. Would be awsome if the game left You use all the tile before leveling up, as often I had more going on on the map and felt a bit disappointed that I couldn't loop some of the prepared knots! :( Very cool game!
Thank you! That's a great idea about not getting rid of the tiles .. the other related comment I've had is that it's sometimes disappointing when you are building a massive loop and you accidentally cause a small sub-loop that clears those tiles! :)
