As the Bunny, you want to make small hops but no bounces. That's really easier said than done, so try to minimize bouncing high. Sometimes when you bounce you need to make a sharp turn and you don't have enough time. With hops you have enough time to move left or right. You will make to the end of the level very quickly because it is not a very long level.
As the Duplicator you want to keep an eye on your duplicates because they may change gravity while you are jumping and that can confuse you and make you fall into the void. If you are about to fall make sure one of your duplicates is on a platform and close to you so it doesn't disappear and you can become that duplicate. With his small jumps you can easily get to each platform.
For the Pastafarian you can walk on your bridge and the platforms but be careful to keep an eye out for gaps in the bridge or you might fall into the void. You need to jump at the end but you are already at the second to last platform which is very close to the last platform which is the end of the level.
