Arrow keys or WASD to move. Space to swing your sword. R to restart a level. The story and other instructions are explained in the game. I might add more levels later.
This is kind of like a prequel to my other project, the Swordsman's Last Stand: https://scratch.mit.edu/projects/397455095/. The music "Crazy Train" by Ozzy Osbourne. Yes it's generic, but it's my first platformer.
