Neural Repair

ATTENTION OPERATOR: Congrats on volunteering to repair a dying AI! (You didn't volunteer.) Light every tile. Do not retrace your steps. In this puzzle roguelike, avoid traps, fog, and that red thing. Should your stability hit zero, all progress will be wiped. NEXUS thanks you for your sacrifice!

Restore the System. Survive the Darkness.

Neural Repair is a puzzle survival roguelike set inside a dying AI. Navigate corrupted neural pathways, light every tile in each sector without retracing your steps, and keep your stability gauge from hitting zero — or face the consequences.

The free demo is available now.

Core Gameplay

Every sector asks one thing: light every tile on the grid without retracing your steps. Simple in concept, demanding in execution. The deeper you go into the network, the more complex and dangerous the sectors become. Every route is a calculated risk. Every move carries consequence.

The Network Is More Damaged Than It Appears

Corrupted sectors and dangerous anomalies, left behind by an unknown catastrophic event, stand between you and full restoration. Trap tiles lurk in the grid — remnants of whatever shattered the network. Disarm them by lighting the surrounding nodes before you step on them, or trigger a short circuit and watch your stability drain. The deeper you go, the more hostile the damage becomes.

Fog of War

You can't always see what's ahead. Undiscovered tiles are buried in drifting fog until you reach them, so every step into the unknown is a gamble. Plan your route with what you can see, and scout carefully before you commit.

One Run. No Mercy.

Stability carries over between every sector. Every mistake follows you, and the further you go, the more it costs. If your stability hits zero, the network collapses and your progress is wiped. This is the true Neural Repair experience.

“NEXUS reminds you that failure is a learning opportunity. Your progress, however, is gone.”

A Story Hidden in the Network

Something is wrong with NEXUS. The network doesn't just need repairing — it has a past. Recovered data fragments surface as you go deeper, revealing the truth one corrupted piece at a time. The deeper you go, the darker it gets. Not everything is what it seems. Some questions are better left unanswered.

Six Unique Protocols

Unlock and master six tech-themed characters, each one fundamentally changing how you approach the grid:

Signal - the base protocol. Pure puzzle solving, no safety net. Every run begins here.
Pulse - lights all surrounding nodes. Rewards careful positioning and planning ahead.
Glitch - passes freely over lit tiles but is stopped instantly by unlit ones. A corrupted protocol that plays by different rules.
Disrupter - randomly toggles tiles on and off. For players who thrive in controlled chaos.
Admin - a slow-charging meter that illuminates large sections of the grid at once. Unlocked by proving your mastery across the network.
Virus - exclusive to Condemn Mode, coming in the full release. Tiles start lit and must be turned OFF instead of on. A completely different challenge.

Special Tiles

As you descend deeper into the network, new hazards emerge from the damage:

Ice - step on and slide until you hit something solid. Momentum is everything.
Fragile - cracks on the first step, falls through on the second. Plan your route carefully.
Mirror - inverts your controls until you find another mirror to cancel it. Don't get turned around.
Corrupt - drains your stability while you stand on it. Move fast or pay the price.
Trap - short-circuits on contact unless disarmed. Light every surrounding node before stepping on it.
Switch & Locked - find the switch before the locked nodes will open. The exit won't wait forever.

More tiles are coming in the full release.

Data Shards and Upgrades

Disarm trap tiles to collect Data Shards — fragments of corrupted data recovered from the most dangerous sectors of the network. Perform well and survive longer to earn more. Between sectors, spend your shards on upgrades that change how you approach what comes next. Every decision compounds. Every run is different.

Go Deeper

Neural Repair doesn't end. The network goes deeper than any single run. Each attempt takes you further into the corruption, reveals more of what happened, and tests everything you've learned. How deep can you go before the network wins?
