Controls and Performance Tips: Arrow Keys - Move, Crouch Space Bar - Jump (hold/tap to control jump height) D - Dash (can dash walljump now!) X - Fire buster, hold to charge Z - Slash Z Saber Jump onto walls to wall grab. Hold the direction facing the wall to hang on, or else press Space Bar/let go of the key to let go of the wall. //// If the game is running slowly, try turning down the key-repeat speed of your keyboard in Control Panel. Also, Scratch tends to run faster in Firefox as opposed to Google Chrome for me. Try turning off hardware acceleration in your Flash settings, as Scratch doesn't support this anyway. Just right-click on the top bar in the editor or on the player in full-screen mode.
