This is great - 5*'s for the first few days. Unfortunately as with all these games there comes a point where progress is so slow that it's not worth playing anymore. Took me about a week. I've spent £25ish on upgrades etc. I'm on Planet Mamek and now, even overnight collections (with all upgrades) arent enough. 1 overnight collection = 1 property upgrade. The money doesn't come in fast enough to make this interesting anymore. I log on upgrade once and then wait overnight again. Annoying.
