The enemy is unseen.

The setting: a spaceship. Reality is being consumed by the “nightmare” seen by the crew in cold sleep, leaving the vessel half-ruined.

You must traverse between the real world and the nightmare, rescuing the remaining survivors.

Your only clues are the signs of the nightmare leaking into reality: monitor malfunctions, sudden shifts in temperature, and strange radio signals.

Your tools are a gun, a repair kit, and the Dream Shader—the only device that can visualize the entities from the nightmare.

Navigate through a procedurally generated ship, using a limited set of resources.

Will you fight the nightmare, or avoid it? Will your health last, or will your sanity give out first?

When and where you use your resources—each decision, each second—can mean life or death.

An intense, condensed roguelite horror experience awaits.

The nightmare has a name: “Heavy Dream.”

A fatal risk humanity accepted in exchange for technological advancement.

• Distress calls echo in the dark

  Explore ever-shifting, procedurally generated zones. Track down essential supplies and cling to the faint hope of survivors.

• An invisible threat

  It cannot be seen. But signs of its presence are everywhere—flickering lights, static on the radio, malfunctioning doors, groaning corpses. Pay attention to these signs bleeding into reality and locate the unseen enemy.

• A high-risk, high-reward mindscape

  Let the enemy get too close, and you’ll be dragged into the nightmare world. There, enemies become visible—but if your sanity hits zero, it's game over. Will you stay and hunt, or flee back to reality? Decide instantly, based on the situation and your remaining resources.

• Choices in the face of despair

  A collapsing spaceship. Resources nearly gone. In this extreme scenario, where repair, combat, and exploration are all trade-offs, you must make the boldest—and most careful—choices to survive.
