I have decided to made the core elements (reusable assets and scenes) of Escape From The Void and the ten levels of the demo project freely available on GitHub.

Technical Informations
Code is split between two distinct git projects:

• EFTV-Core: Scripts and reusable assets. It is not meant to be used by itself but as a submodule.
• EFTV-Demo: Godot Project. Full content of the free demo as an example of how things works and how to make new levels by your own ;)
