It's driving me nutz - I can't remember the name of a game I had ages ago... I can't see it on my previously purchased apps on the Play store but it was definitely on Android. Basically you had these floating platforms with cardboard boxes (with faces on them) and bottles. The idea was to shoot the boxes off of the platform, without knocking over any bottles. It was surprisingly good fun and I'd love to get it again but darned if I can find it?
