Have you heard of the many-worlds theory? It says that somewhere out there, there exists a reality where your favorite indie game character is about to say the very thing you're about to type.
Alternate Universe Playbook helps you turn that into comics* & *visual novel scenes.
Thank you to the participating games featured at launch -- please check them out!:
We hope you have fun making & sharing with AU Playbook~ This program was quite an effort to develop, but we will keep it free and open to the community, with more titles and characters to come (and more ways to import custom assets).
If you've any suggestions or thoughts, please feel free to post on the Steam forum board or our Discord. Cheers & thanks everyone~
