This is level 9 of Plan A.
To finish the level with the Child, at the start high jump and search for a landing with many other tiles nearby. You can restart the cycle until you finish the level. This is an easy way since all you need to worry is finding a landing spot and there are quite a bunch of landing spots.
Remember: you can high jump by holding your jump button. This will help with a TON of levels and remove some of its difficulty.
If you are using the Bunny, repeat but you can jump twice by jumping right when you bounce. It´s the easiest way to beat this level.
