The goal of the game is to ascend all five levels to reach the surface. Along the way you can collect treasures and save a few stranded ladies. Lava and water flow to fill gaps and will kill you if you stay in them too long.
Defend your castle as a wizard by casting spells on enemy robots in Tech and Magic. Destroying robots will give you crystals, which will allow you to unlock and upgrade spells, and give your castle better defences.
