The wall jumps are a little weird, it's the thing where you don't do it the way you think you should, you have to do it the way the game wants you to, but it's really easy once you understand how the game wants you to.

Step 1: Make sure you are doing a rolling jump (a walking/running jump)
Step 2: When you hit the wall, pull back in the other direction for about half a second before jumping, you should see Samuses sprite change during this, this is when you want to hit the jump button again.
