Fun game, though repetitive as people keep saying. Also found a little bug/cheat - If you click a building you don't have to bring up the option of where to place it, then click a building you already have on the bottom bar it'll upgrade that building and still allow you to build the first (puts you on negative cash but means you're going to get way more money back faster).
