Updated the game to version 0.2.8

Steam Next fest is coming up in February and Abject Abyss will be included, so I’m updating the demo to the latest version ahead of the event. It's not a big one, most of the work I've been doing is on everything past the demo, but a few things have changed and I want to make sure next fest is up to date.

• Mostly just built up small tweaks
• Slightly re-paced the start of the chase section in the demo
• Simplified demo end screen
• Small text updates
• Changed an email on Ernest's terminal
