Lighthouse Mage: Idle Defense

Idle tower defense on a tiny island. Your lighthouse fires magic bolts at crabs, jellyfish, eels, pirate rafts and huge sea bosses that come from every side. Spend gold on damage, defense and magic during the run, collect pearls and relics for permanent upgrades, unlock four spells and sail on to icy, volcanic and abyss seas. Steer the lighthouse beam yourself for double damage.

The lighthouse shoots by itself. Tap upgrade cards at the bottom (Attack, Defense, Magic) to spend gold on damage, attack speed, health, armor and income. Hold and drag on the sea (mouse or finger) to aim the lighthouse beam: it deals double damage. Cast spells with the buttons on the right. Every 10th wave brings a boss. When the lighthouse falls, spend pearls in the Harbor on permanent upgrades and try again to reach a higher wave.
