This turned out to be surprisingly relaxing and fun, similar to some of the old Atari 2600 games.
I love the shaking and noise of the dishes when they're dirty, and it's so satisfying when they get clean. It actually reminds me a bit of... actually washing the dishes. :D
I played for 50 levels, but then I lost interest--nothing really changes from one level to the next, other than the position and number of dirty plates, cups, and forks.
