Hey bekb,
The controls are good. I feel like it would be better if the "bounce down" attack triggered on key release only. Sometimes I only want to charge, but I have to bounce down also because it triggers on both key press and release. The special attacks made the game a lot easier for me. I think "For high skill players" is a bit of an exaggeration. It's was my first time playing the game and I found them easy to execute.
I really like your use of visual effects by the way. The attacks all look very satisfying.
