Description

This is a puzzle game about filling in eight-by-eight maps of dungeons while observing four simple rules:

1. Every row and column of the grid must contain exactly the labeled number of walls.
2. A cell contains a monster if and only if it is a dead end; i.e., exactly one orthogonally adjacent cell is open.
3. A treasure chest must be contained in a three-by-three area of open space with only one entrance or exit.
4. No two-by-two area of open space may exist outside of a treasure room.

It is modular and can be played with plug-and-play level packs. A level generator at the github repo can create properly-formatted level packs (documentation upcoming). One pack is included with nine levels.

Source code is available at https://github.com/ariajd27/dnd-ce.
