This is a flash game where the only objective is to get as high as you can. To do this, you must bounce on the bells that descend (which also get smaller as you progress higher). The more bells you get, the more score they're worth. Probably the only other important thing to remember is that if you bounce on a dove, your score doubles.

Here is the game:
