I've reuploaded the v0.1.2.2 release with a hotfix as it called for a missing music asset in the prologue. You can redownload the game to fix the bug, or navigate to "\Skirjasaga\www\audio\bgm" and copy + paste the "FridayAfternoon.rpgmvo" file and rename the duplicate file to "Friday Afternoon Loop.rpgmvo".
Sorry for the inconvenience.
