We finally have chapters 6, 7, and 8 in beta! The plan is to release chapters 6-12 bundled together, the same as chapters 1-5 were. So voice acting will be added to all of these new chapters once Chapter 12 is in beta.
In addition to the writing and visuals for Chapter 8, this update also includes:
adjustments to earlier chapters based on feedback (especially beta feedback on chapters 6 and 7)
a handful of improvements to visuals in existing chapters. For example, the "hologram" that appears when calling someone on the phone now includes an animation.
