ActionPotato 

In this cute game, potatoes are constantly being tossed from the right side of the screen. Your goal is to catch the fresh potatoes and avoid the rotten ones by clicking on the happy little cans on the table; doing so makes them jump in the air and catch anything they touch!

Catching a string of fresh potatoes without missing one will result in a combo point bonus, but catching a single rotten potato (I thought these were rocks until I read the game description) knocks the can off the table, disabling it until one of the other cans can manage to catch a flying heart. The stream of potatoes starts out one at a time and accelerates to the point where you have to time your jumps very carefully indeed to stay alive. When all three cans have been knocked down by rotten potatoes, you have the chance to submit your score to an online leaderboard, which gives you a "grade" based on how you stack up to other recent players.

I'm a big fan of Sunflat's games. Their broad variety, distilled simplicity, and charming graphics make them the best collection of free games available on the Mac App Store. I just wish the developers hadn't put in so many ads for their other free apps, as these detract from the experience and seem to serve no monetary purpose.

Sam's Protip: The cans on the left side are more valuable; they can catch more of the potatoes and can also see them coming earlier. I recommend using them until you have no choice!
