Farmless Ridley any% hard

Saves a bit of time, and you don't have to wait for the fireballs, so no RNG involved.
Of course you need to adapt, depending on the damage boost. If you get dboost to the right, well, you still added extra damage, you can tank and fire missiles, or start charging already.
If you get a left dboost too far to the right, you will deal more damage that a dboost to the right, and can start charging.
If you get dboost too far to the left, Ridley will turn around. If you have at least 3etanks (249 energy), you are safe. Otherwise, play safe
