Improvements: Now while playing a flute, the interface shows which buttons you can use. During boat races, now the floor shows the shape of the circuit to avoid becoming lost. Walking speed when using the light spell has been increased. When using the light spell on a crystal, now a popup appears showing the buttons for aiming. Mole's hitbox when being hurt by a boulder from Yami is now larger. Fixed bugs: A few players used to lose their minecart in the room where you switch tracks using the waitress.
