Curiosity-aping puzzler Furiosity is out right now for Android and iOS
AAAAAAAAAAAAAAAAAAAAAAAAARGH

Hi there. My name's Harry.
You might remember me from a piece about Curiosity I wrote called The Curiosity Cube Diaries. The whole ordeal lasted about four months and I went a bit mad.
Or I pretended to, anyway.
FuriouslyBart Bonte had a slightly saner reaction to Peter Molyneux's cube-tapping game / social experiment. Yep, Bonte created Furiosity.
This was a browser game that 'gave' reason to Curiosity's block tapping, and featured a life-changing prize (awarded to the first person to finish its 40 levels).
Well, Furiosity is out on iOS and Android now. It has 144 levels, no life-changing prize, and an awful lot of blocks to tap.

Rather than just tapping mindlessly here, though, there's a logic to each of the levels. You need to work out where to tap, and when, if you want to clear a layer and move on to the next.
It's simply presented. Oh, and it might make you go mad (but in a good way... rather than a frustrated, eventually dribbly way.)
You can pick Furiosity up from the App Store right this second for 69p / 99c, and from the Google Play Store for 83p / 99c.
