01

The Kingdom

A beautiful world that feels strangely wrong.

A mysterious child is entrusted with finding a missing prince. Accompanied by the Eye, explore the Royal Forest, the Mushroom World and the Forbidden Cave.

SelkoMadd combines hand-drawn 2D artwork with 3D level geometry, layered parallax and carefully crafted lighting to create a side-scrolling world with depth.

02

Risk / Reward

Your life is your key.

Trade part of your health for magical blocks. The cost makes the journey harder, but opens otherwise unreachable places - and gives you more opportunities to uncover the kingdom's hidden lore.

03

Rhythm & Bosses

Boss encounters built around music.

SelkoMadd's boss encounters mix rhythm, timing and relentless motion. Music is not decoration: it drives the identity and intensity of each confrontation.

More than ten original tracks in the demo. The full game explores jazz, metalcore, techno, classical and more - composed in-house by the team.

A Story to Reconstruct

The truth is not simply told to you.

Fragments of lore are scattered throughout the kingdom. Find them, connect them and question what you think you understand.

What happened to the prince? Who is the child? What is the Eye? Why does this world feel familiar?

Something is wrong.
