Cardboard Catacombs · Development

Building Cardboard Catacombs one system at a time.

The first playable foundation is in place.

Now Cardboard Catacombs keeps growing.

Development Journey

From Project Blueprint to Cardboard Catacombs.

The project has grown through experimentation, feedback and increasingly ambitious systems.

The Idea

A Creative Question

Around 2023, Amy's love of level editors and her experience making Team Fortress 2 maps in Hammer began shaping a more approachable way to build 3D levels.

Prototype Hero

Proving the Loop

While still learning Unity, Amy created an early Project Blueprint prototype for a college competition with support from an approximately €800 development budget. The rough but playable build helped validate the central idea.

Skill Building

Learning Through Other Projects

College work, personal projects and smaller VR experiments broadened Amy's development experience before she returned to the concept.

Game Lab

Rebuilding the Editor

Project Blueprint returned through Game Lab with a stronger player-facing editor focused on making complex 3D spaces emerge from simple actions.

Cardboard Catacombs

From Editor to Game

The project evolved into today's action-adventure framework, adding combat, responsive enemies, connected objects and a clear treasure-chest objective around the creation tools.

The Foundation

Turning a level editor into a game you can build and play.

Cardboard Catacombs grew by bringing three key parts together.

Planned

More Playtesting

Watch new players build levels, then see whether other people understand and enjoy playing them.

Planned

More Gameplay

Add new ways to move, hazards, interactive objects, goals, enemy behaviors and enemy types.

Planned

Performance Testing

Make sure bigger, busier player-made worlds continue to run smoothly.
