I believe I have them ALL. Because I played it a *few* hours. This is one of my first game on phone, and I've played regularly (a few hours a week I think) for a few months. I wouldn't be surprised if I had +50 hours even if I'd be more serious and say +20 hours of gaming.
I prefer Grimbingo... mainly because I was in the stream when they were messing around with the skin idea, and kinda ended up inspiring it. (wow, bragging while being humble is hard.... or is it being humble while bragging?) XD
