I haven't really played long, so please take my words with a grain of salt. This is a game that works on a f2p model, with an Advertisement framework attached. If you want to do a lot more than what you do, you need to watch an ad, if you play within the free content, you still get ads every few minutes or so. The game's premise is fine and the aesthetics are simple and the art direction harmonizes it well, but I am not a fan of the forced ads and have uninstalled the game. Still good game tho.
