After a long time coming, version 2.22 of Death Rule: lost code OVERDRIVE EDITION is out. Below is the changelog:

• The Extras menu has been activated, which will allow you to access the CG Gallery, Music Gallery, Information Page, and Extra Scenes. You will receive the proper flag to unlock it upon starting up the game, provided you cleared all three Episodes already. Otherwise you will unlock it once you get the proper ends for The Final Rule, Lost Code and complete Untold Stories.
• CG Gallery is now available. Some leftover CG’s have been also included as a bonus, and will unlock upon completing the game 100%.
• Music Room is now available.
• The Information page is now available.
• The Extra Scenes page is now available.
• Support for Ren’Py’s Self-Voicing option has been improved. Some of
  these support changes went through in Patch 2.02, but they were incomplete. Now there should be descriptions for the character as well as voicing for the Yes/No screens.
