In level 9 there is a little improvement I discover (I didnt see in the runs any use of this, but maybe I missed it).

When ordering the remote control, the red rope can be not used. Get to the mail box with out the rope. To get back, jump on the wall/tree in the middle in the swamp. The crocodile will be starting to go back. When it gets back, jump back to the island, and run towords the crocodile, and get pass him from the right. from there just jump to the remote controll.

This probablly save only few seconds, but it's nice trick
