I've just uploaded a new version of the latest update that corrects an error on my part that occurs during chapter 4. An NPC blocks a hallway in chapter's dungeon that prevents progress. This version has removed it and the game should work as intended.

IF YOU HAVE MADE PROGRESS IN 4.1.1, YOUR SAVE FILE SHOULD STILL BE COMPATIBLE WITH THIS VERSION! PLEASE PLACE YOUR OLD SAVE INTO THE NEW VERSION'S SAVE FOLDER!

The Android version is still pending. It should be uploaded soon.
