Dear Players,
We offer our most sincere apologies. Due to a mistake by our team, we incorrectly uploaded the updated Demo version as the Early Access (EA) version to Steam. This resulted in many players finding they could not unlock Chapter 2 and Chapter 3 after updating.
After discovering the issue, we have now uploaded the correct EA version package. Once the game is updated, the normal unlock progression will be restored: completing Chapter 1 will unlock Chapter 2, and completing Chapter 2 will unlock Chapter 3.
Please rest assured, your save files will be fully preserved and are not affected.
We deeply apologize again for the confusion and inconvenience this mistake has caused. Thank you all for your patience, understanding, and support!
