What, you mean they actually can eat sandwiches!?!
This is a great animation. The artwork is in a feel of a comic style and the motion is smooth. Also entertaining to see the joker eating a sandwich with gusto and expecting to see something crazy to happen: but alas, he goes about his way unscathed.
Sadly though, there is no sound or music or anything in that manner. I hate to even dock down the score on a great flash, but to the viewer it would be nice to have some smacking noises of glee while eating said sandwich.
But please, don't stop there. I would love to see more of your work further in the future. And thanks a bunch for sharing this, keep up that great work of yours.
