About

Dungeon Guide

Read full description

You are the Dungeon’s Guide. Your mission is to lead adventurers safely through the labyrinth. Every move is a test of your logic, and every decision can change the fate of those who enter. The dungeon is a roguelike sliding puzzle, where each move can change everything. By moving panels, you can alter the paths of adventurers and enemies alike. Navigate carefully to avoid traps and attacks while aiming for the goal. Your strategy and clever thinking will be the keys to success. If an adventurer’s HP drops to zero, it’s game over. Don’t forget to heal with potions or restock at the shop! With enough gold, you can even hire bodyguards-loyal allies who fend off enemies for you.
