About this game

Closed Loop Dungeon is a dungeon puzzle game where you draw a single line to divide space and solve each stage.
Study the placement of the hero, keys, doors, bombs, buckets, warp gates, and other objects, then decide what should go into each area as you work toward the exit.

The rules are simple.
Just draw one continuous line.
But how you divide the stage changes the entire solution.

As you progress, you will need to cancel bombs with buckets, read the timing of walls and warp gates, and design multiple spaces at once.
The controls are simple and easy to use on mobile, but the later stages offer a satisfying logical challenge.
It is a dungeon puzzle game with a great sense of discovery, where finding the right solution feels genuinely rewarding.

Features:
- A fresh puzzle concept based on dividing space with a single line
- Stage-based gameplay that is easy to enjoy in short sessions
- Brain-training style logic puzzles with satisfying depth
- A variety of mechanics including keys, doors, bombs, buckets, and warp gates
- Simple controls with thoughtful single-player puzzle design

Divide the space and clear the dungeon.
Open a path forward with a single stroke.
Draw one line, Divide the dungeon, and Escape! Solve clever logic puzzles.
