I discovered a bunch of optimizations and decided to compile them into a run!

0:10 You can jump from the ground with the seesaw into the tree branch. You can do it without an air shot but it's more precise

0:14 Instead of going the long way around, you can jump on top of the pear enemy to get to the anvil platform. You have to wait until slightly before it lines up with the middle line of fruit to the left before jumping

0:46 You can ride on the green plaftorm and reach the second branch with an air shot

1:33 You can skip anvil #2 entirely by jumping from the green platform

1:46 There's a hidden platform with a spring below the checkpoint. You can use it to skip getting the key
