Demon Lord Tamer is actually a "tamagotchi" virtual pet simulation.

You must evolve your own pet demon to destroy the world. You have to feed it, play with it and clean it. This attention-hungry little demon needs your affection. The most important thing you have to do in this Click & Point based game is to be a good clicker.

It will evolve every 200 clicks as it fulfills the needs of our virtual demon.
The faster you meet the needs of our virtual demon, the faster it will evolve.
