Credits
Built on other people’s generosity.
Darkerlight is built on work that was given away — engines, tools, typefaces and art, released free by people who asked us for nothing. Some of it we are required to credit. All of it we want to.
A gold edge marks work released into the public domain: given away outright, no credit required. Where a project takes support, we have linked it.

A note
Nobody asked us to.
Several of the people above released their work into the public domain and asked for nothing at all — no credit, no fee, no conditions. They did not have to do that. Without them there is no world here to look at. Where they take support, we have linked it; if you make games, they are worth yours too.
If we have used your work and got the credit wrong, or missed you entirely, tell us and we will fix it: [email protected].
