Hello, this is Jun, the creator of YAKG!
Some players have reached out about having strange issues with playing YAKG after allowing Steam to auto-update them to Version 1.1. Issues include--but are probably not limited to--seeing an error message when starting a "New Game", getting soft-locked in a branching decision for Part 2, seeing incorrect progress in the "Status" screen, and being unable to access Part 1 investigations due to "New Game" not correctly resetting progress.
These are issues likely caused by Steam's automatic updater only updating game files that it perceives to have changes. So the TL;DR solution:
PLEASE UNINSTALL THE GAME, THEN RE-INSTALL IT
Doing so will likely resolve all of these issues, but if issues still persist, then unfortunately, you may need to just do a full reset of all of your save data. Please search up how to delete all save data for Ren'Py games, or ask in the Discussions if you need assistance with this!
ALSO NOTE: re-installing the game does NOT resolve any issues you may have with loading save files created in Version 1.0. Please look inside "Help" and "Config" to utilize the game's Skip features, and sorry for any inconveniences this causes!
Best wishes,
Jun Kakeru
