You're extremely welcome to create videos of Cardinal Chains and upload them to Youtube, Twitch or similar services. Please note, however, that the game contains a licensed soundtrack, but it's easy to work around this problem. Basically, you have two alternatives:
- Disable the music: open the options menu and set "Music Volume" to "0%" or "Muted"; or
- License the music from Soundstripe: all songs in the game are licensed from Soundstripe. If you make videos for online platforms, chances are you've already heard of this service or may even be using it. If you have an active subscription, you can license the game's songs for free. A playlist of songs featured in Cardinal Chains is available for your convenience.
If you have any questions regarding videos or any other issues, please send an email to firstname.lastname@example.org and I will be glad to help you out.
