Ha, I knew this question was going to be asked but over the past week I've discovered codes to implement in an attempt to balance the moves out. When I release the next preview video I'm gonna make a detailed write up explaining the new mechanics I've integrated onto Dark Samus but here's an abbreviated explanation of how the moves work so far:
-The Special N Air Charged- Big Phazon and Plasma Beams (shown in the last two preview posts) can only be used over a certain damage % or else it will be just be an enlarged version of this:
-The Plasma Beam is a stronger version of the Phazon Beam and has a cool down so that it cannot be constantly used. DS's arm cannon will ignite will a flame graphic to indicate that she can use the move again.
-DS points the Plasma Beam directly below her and sweeps it forward like this (watch the DS clone to the left using the beam):

Still thinking about how to make this move better but this is how it is so far.
