Okay, I've got at least one tip for you, whenever your aiming for a platinum crest, try to get as many combos as possible. Like, if you see a monkey, that wants to throw you in a certain direction, don't jump to him right away. instead look around and see if there is anything that can help build up your combo so that every bannana you get, will be worth more points. for example: on the first level, you come to a monkey, that wants to throw you up a cliff. but before you do that, run towards the wall. stop inches, before you get to the wall, then do a backflip onto the wall, and slide down the wall until you get about halfway down, and then jump off of the wall, and grab the monkey's hand. have him throw you and then get into another monkey. That's six combos right there!
