About the game

Narrative

The narrative is an integral part of Twofold Tower, and is made up of three distinct parts:

Dialogue, in which a handful of colourful characters try to come to terms with the world having ended.
Satirical snippets, which flesh out the broken fantasy world in which the game takes place, written in a style reminiscent of The Hitchhiker's Guide to the Galaxy.
Poetry, largely centred around the perils and limits of reason, and employing a mixture of sincerity and humour.

While never obscure or difficult just for the sake of it, the narrative does respect your intelligence, and brings together ideas from many different areas, including science, philosophy, spirituality, and religion.

Goodies

Every copy of Twofold Tower includes its soundtrack in a lossless format, and three exclusive ebooks:

However, there will still be usage restrictions ensuring that Twofold Tower remains commercially viable.
