You are Sir Gallant, a knight who has been blessed with the power of King Midas in a way that can be turned on and off! With your power you feel a confident enough to take on the very foolish Obsidian Arena, full of perilous foes!

Controls are explained in game, but here they are:

A/J/Left: go left. Pushing into walls while airborne slides down them.
D/L/Right: go right
W/I/Up: vertical movement. While on floor this is a jump. While in air pushing into a wall, this is a wall jump. While head feathers touch ceiling, this is a ceiling slide.
Enter, Space, or Shift: throw the Midas Punch.

TIPS: you have more range than you think. The seeking orb can be tricked. Additionally, you get a little display with your character that shows the direction and distance to it so you can keep track of it when it's off-screen. Sometimes it is better to wait a little so that the enemy uses its shot and leaves itself open from another angle.
