You can jump through most platforms from below and land on top of them.This lets you do some damage boosts that would be impossible otherwise. When you only tap JUMP at the end of your jump your hitbox will be slightly higher than when using the helicopter.If you press "JUMP" very briefly you can avoid going onto platforms that are near above you.If you start the helicopter at the top of your jump, you will reach a little extra height.The longer you hold "JUMP", the higher you jump.When something is blocking you from jumping, jump as soon as you are past that (for example ceilings).
If the platform is diagonal jump at it as soon as you can reach the highest point which you can reach by jumping.Jump as early as possible onto the next platform.
