Hey! Thanks for playing our game. The demo is supposed to "end" after that scene but it bugs out; we'll be adding the remainder of Chapter 1 ASAP. Your save data will carry over and you'll resume in that scene with your data restored.
We're working on improving performance and adding saving and loading in the next build, so we hope you check out what's in store! We've fixed the Hermes bug and will upload that shortly. We hope to make these changes within the next 12 hours.
Thanks for your feedback!!
