How can I find the daneila way
Daneila is not in the demo. The demo is just a sample of my work taken from a small section of the game. She's accessible in the Beta from Patreon along with all the other characters.
If you are a Patreon and are wondering how to access her in game you'll want to choose these key options: Do not post the rose, and do not meet Rebecca/Mark's coworker.
