Remove bricks by using magic spells and earn points. Use the points to learn more spells and upgrade your character!
Move your character with Arrow left and right. Press X for Orb of Destruction spell (a big explosion). Press Z for Shadow Orbs Attack (splits your orb into multiples).
Before every level you can use earned points to upgrade your character's attributes and to enhance the spells.
Don't worry for the orb, it cannot leave the screen.
