itch.io

Hello! So after long deliberation:

• You can do whatever you want with the PDF (it's more like bonus content, not really a part of the game!), so feel free to make it have as many words as you want, etc.
• We're generally fine with the idea of having an extra screen that you can access from the main menu in which you can do the cross promo. However, please use this in good faith: as long as it doesn't go against the rule of making your game a self-contained story, it's okay.

However, I'd like to mention that as an alternative, itch lets you create embeds that you can then paste into websites (I've previously done it in the project pages of my other games). So for an easier way to do the cross-promo, you could try this instead!
