The 5 perfect badge is pretty easy actually. Don't do the shortest jumps, but jump earlier if you have to. It's easier to hit if you can control how far you'll jump. Getting to 15 000m on the other hand ... It's not good for your eyes.
You a small thingy I found. When you use the float action, if two Dibbles jump into at the same time or a bit after eachother they merge into one, and thus you can't win if you arent playing slowly :( Great game otherwise though
