Demo Sonic BTS Redux - Proof of Concept DEMO

This is a project I've been working on for the past few months. The original Before the Sequel is a game I hold very colse to my heart, but it didn't age as gracefully as other fanworks.
That's why I've been recreating the game from scratch, fixing the physics an overall presentation, as well as adding ne features from more recent games.
Only the first act of HillTop Heights is playable in this demo as its only a PoC, but if everything goes well there will be a bigger demo at SAGE '23, so I'd really appreciate all of your feedback.
