Overview

Currently I am leaning toward a spatial puzzle game, heavily inspired by DOOM II and Vampire: The Masquerade - Bloodlines.

Adventure

Basically, it would be an 3D adventure game, but with multiple differences:

1. Gate costs will be integral instead of binary, via resources. (Gating itself is still binary)
2. Short playthroughs
3. Limited persistent state
4. Randomized state
5. Either minimal or no dialog

Interaction

An important feature I want is a Densely interactive environment.
