Cool, pretty straight forward puzzle/matching game. I like that there's different ways to clear lines, and you can build up and prepare for matches but wait til you really need to. I couldn't get the Cross 2 lines to work at all though, and there were a few times where I would clear a line and more buildings would disappear too. I couldn't really figure out the rules for why though. If the starting tutorial was expanding, this would be a super easy to pick up game!
