Yeah, I’ve been sort of levelling a score of pets… but then Ndemic released Plague Inc. for Android. It’s very similar to the flash game Pandemic, and while it chews the hell out of my OneX’s battery, it’s great for that casual game fix. The free version’s only limit seems to be that you can’t pre-cook your infection or fast-forward, but I got the full version because it’s cheap anyway.
Plus you get to kill everyone in the world with a horrible plague. Everyone wins!
