Idle Slayer is an incremental game with idle and active playstyle mechanics, medieval pixel art visuals and retro 8-bit sounds and music.
Start from nothing and grow as a Slayer.

Travel across countless worlds, collect souls, and become stronger with every step.
Jump, run, and slay enemies in many different ways as you build your power and uncover new ways to progress.
What begins as a simple journey quickly turns into a vast adventure filled with upgrades, challenges, and surprises waiting to be discovered.






Every decision matters. Some will help you move faster, others might slow you down.
