No time2play? Try Time4Cat. It's an over-in-minutes, single-mechanic flash game that's about as much like a flash game as you could ever imagine, at least in terms of controls. It's also about a cat eating untold amounts of food on a busy crossroads and helplessly controlling time as it does, so you'll want to play it anyway. The faster you move, the more you score from each food-munch - but the faster the pedestrians storm about the place and the more danger you end up in. But what does it all mean? Well, it's a metaphor for a time-controlling cat eating icecreams in the middle of road, silly.
It makes no sense whatsoever but it's charmingly-drawn and, as Kyle Orland observed, it'll devour your afternoon. Not quite this month's Robot Unicorn Attack - no Erasure, for a start - but definitely sporting some of the same brain-cuddling compulsion.
