Use the arrow keys to move

1 key to cast a fire spell (costs 10 mana, does 25 damage)

2 key to cast a lightning spell (costs 30 mana, does 10 damage, stops enemies attacking temporarily)

3 key to case an ice spell (costs 50 mana, does 10 damage, stops enemies moving temporarily)

4 key to use the items!

(In 2 player mode, player one uses WASD instead of arrow keys to move and player 2 uses the number pad instead of the normal number keys to cast spells)
