Sky Islands Clicker

My first entry into LD. In Java programmed Clicker-Game.

You are a wizard who used a spell that makes him the best wizard in the world.
Accidental the spell destroyed the whole world, leaving a magic crystal. But three islands that form a small world refused to collaps. But you, obsessed from power, want more. Collect mana and gain more power, until there's just you and the crystal.
