By far the best feederism game I have ever played, and I've seen quite a few. The art style and progression in both appearance and interactions is excellent. 
I think all that holds it back is some inconviences, like not being able to pick up the maximum amount of an item, to save time when going back and forward feeding your coworkers; and I think some systems like the fitness program could be explained a bit more in dpeth too. However, other than those nit picks, its perfect.
