Use WASD or Arrow keys to move around and jump. Dodge the objects and try to survive. You can crouch by pressing S or the down arrow key. (Gives you invincibility to swords) If you crouch before you jump you will jump higher than regular jumping.
Credits to @ETHAN_2201, or @-Really_EZ I made this game insane. btw, watch out for the carts. You WILL NEED CROUCH JUMPING.
