You are a DOPPELGANGER who has to face five trials.
In every level you must kill every enemy, after the last one is defeated a new level will start.
There are multiple creatures in the dungeon, whenever you kill one creature you become a copy of it.
There are five level of power (white, blue, green, orange and yellow), whenever you kill a creature of
your level or higher you gain one level.
When you die you return to your last form with full HP but lose one leve.
If you don't have a form to come back or die at level white the Game is Over
Every creature has three skills, two of them with a cooldown that only goes down when it has enemies in LOS.
When there are no enemies at LOS creatures regenerate slowly
