Delta-Void is a game concept that I wrote with a co-author over a few days in February 2024. The player is a glowing humanoid creature exploring a multi-layered abyss: floating islands, mineral caves, ruins and underground oceans.
The game design document covers exploration with jumping, grappling and magic, and melee, ranged and mystical combat. It has base building and survival around food, water and Void Fluid, a resource that bends time. It also describes co-op, competitive and creative modes.
In the story the player is a scientist on “Project Delta” who falls into the abyss. A separate document walks through the first ten minutes: the tutorial, the first enemy (a void fly that drops a grappling hook) and a hallucination sequence.
The only code is a small Godot 4 movement prototype with isometric tiles. I generated the concept images with DALL·E. Source on GitHub.
