Oneiro

Oneiro is a difficult, randomly generated nightmare labyrinth where you confront fears planted by your caretaker. Children sent to a remote island to overcome those fears enter the Labyrinth in their dreams; they can return home only by conquering it. You explore its four layers, which grow progressively harder and test your knowledge of the game’s mechanics.

Story and setting

Parents use horror stories aimed at their children as a way to change their behavior, unaware of the psychological harm they cause. The children who become victims are sent to The Island, thousands of miles from the nearest shoreline, and remain there until they overcome the fears their caretakers gave them. In sleep, each child dreams up a Labyrinth formed from every fear.

Explore the Labyrinth

Each run randomly generates the Labyrinth, but its patterns and tricks can help you navigate it more quickly and safely as you learn. There are no permanent upgrades or gameplay progression between runs: what changes from your first run to your hundredth is your knowledge and skill with the systems. The game is designed to be difficult but fair.

Weapons and tactics

You can find 20 weapons across five types: Fists, Swords, Karambits, Hammers and Spears. Each type works differently, offering varied approaches to combat. You can fight enemies directly or use objects and mechanics in creative ways, such as throwing knives at a nearby wall to bring the ceiling down on an enemy, or breaking through the ceiling to attack from above.

Items and equipment

Treasures can contain items that improve your stats or grant new abilities. You can collect, duplicate and stack items without a limit to multiply their effects, and find more than 50 pieces of equipment and gear. For example, you can build toward 10 midair jumps, regenerate 20% of your life every 10 seconds, or make enemies explode in a large radius when they die.
