NN555Core

Restore a drifting energy core through compact, tactile puzzle runs.

NN555Core is a lightweight puzzle game built around one core action: swipe adjacent tiles to swap them. Each run asks you to read the board, plan a few moves ahead, and keep the system stable while time and steps run down.

Features:

- Handcrafted campaign levels with rising board sizes and tighter limits

- Locked cells that must be weakened before they can move

- One-way gates that restrict how tiles can flow across the board

- Rotating zones that change the layout after a few successful swaps

- Booster tools that help break deadlocks without solving the board for you

- Local progress saving with unlocked stages and best remaining-step records

The game is designed for short sessions and offline play. Open a level, study the targets, and guide the board back into alignment before the core drains.
