What the SIL Open Font License permits
Summary only — not a substitute for the full license text linked above, which governs:
- You may use, study, copy, merge, embed, modify, and redistribute the fonts, including bundled inside a commercial product such as this game, free of charge.
- The fonts (modified or not) may not be sold by themselves as a standalone product.
- Modified versions may not use the fonts' Reserved Font Names ("Comfortaa" / "Source") without separate written permission from the copyright holders.
- The obligation to keep the font itself under the OFL does not extend to documents or other creative works (such as this game) created using the font — only to the font software itself.
