At this stage in the game's lifecycle, the developers were focused on "hotfixing" the physics engine and progression systems. The key changes during this mid-December period included:
Improved vibration cues for controllers (Oculus Touch and Valve Index) to make the physical interactions feel more grounded.
Right-clicking Part 1 and selecting "Extract Here" using software like WinRAR or 7-Zip automatically pulls the data from Part 2 to reconstruct the full update.
This was one of the earliest "Day 4" or "Day 5" patches designed to address critical stability issues and player feedback immediately following the game's release on December 10, 2019. Historical Significance of the 14.12.2019 Update
Early players struggled with the lack of mid-level checkpoints. While the major "Checkpoint Update" came later, this patch improved stability to prevent crashes that would lose level progress.
