About
Explore, mine, craft, and fight your way through a vast world — alongside an AI companion that's truly yours.
MyDopplerEffekt is a 2D side-scrolling adventure set in a huge, procedurally generated world. Dig from sunlit surface biomes down into deep, dangerous caves. Gather rare ores, craft tiered tools, weapons, and armor, and battle creatures, minibosses, and ranked dungeon-gate bosses as you grow stronger.
But your companion is what sets the journey apart. It has its own personality, moods, and memories — it reacts to how you play, lends a hand out in the world, and grows alongside you. No two companions feel the same.
