Rewrite the dream. Face what follows.

A turn-based traditional roguelike set in the subconscious. Explore shifting dreams, rewrite descriptions of reality, build sentences from equipment, and make environmental reactions part of your tactics.

Play in your browser

Use the Run game button above to begin without installing anything. A desktop browser and keyboard are recommended. The first load downloads the runtime; start with the layer 0 tutorial to learn movement, observation and environmental interaction.

Rewrite the sentence

Open the tamper panel on a nearby target, then choose words, conditions and degree. The preview shows the revised sentence, the imagination cost and the chaos it adds before you commit. A wall may crack instead of vanish. A passage may open. A line of dialogue may take a different turn. This is not free-form typing: the game offers targets, words and conditions, and you decide whether the trade is worth it.

English desktop recording: choose a word, preview the cost, then confirm the edit in a generated combat map.

Build a sentence from your gear

Equipment goes onto an 8×6 association board, not into slots. Position is meaning: the same object can act as a condition, a carrier, a modifier or an action depending on its column. Function words such as and, or, if and else connect the pieces. Read the resulting sentence, check the effect lines, then commit. Rotate, move and rebuild when the dream changes.

Desktop capture: pick up, move, rotate and place equipment, then add AGAIN and confirm.

Make the environment part of the plan

Liquids flow, gases spread, and materials react on contact. Fire, electric fields and structural damage are tools as much as threats. A conductive puddle and an electric discharge can reach a target you cannot. A gas cloud and a spark can clear a room, or backfire. Reactions do not check whose side you are on.

Staged in-engine simulation: ignition, explosion, fire spread, then electric-field activation. Turns are paced for demonstration.

Descend into deeper dreams

Explore generated rooms, caves, corridors and mazes. Discover anomalous sites, meet wandering characters, collect memories and enter dreams within dreams. Adjust your build as unfamiliar situations challenge the approach that brought you this far.
