MOD RELEASED
After waiting over a year for TFarrgon to say something here, or on the Discord they frequent (including DMs), I went and put together the modified files to fix/upgrade v1.06 to what I'm calling v1.06+
This cleans up lots of text, graphics issues, and internal RPG Maker MV coding thingies. And it lets you continue Shimmer & friends' adventures in an unauthorized journey into assets that were already in v1.06 but not visible to the casual player.
If TFarrgon wants this gone, or to use the fixes in further development, then this mod will be no more. And note that savegames from v1.06 probably won't work in v1.06+.
