Move the mouse aim. Click to move. Try to stay on the path (the grass will slow you down.) Hold Spacebar to ready your spells, then press 1, 2, or 3 to cast the desired spell -if you have enough mana. Moving to the top of the screen will bring you to the next area (there's no going back!) Step on the blue mushrooms to absorb their energy and recharge your mana (1/3 of you bar); Careful though, If you absorb too much mana while your bar is full, you will get "Mana Sickness" (You can't cast spells for a few seconds)
