that means that you have double the game labels.Could it be that you only copy the new version into the old game folder? or used Unren?
Just start the game again. Should work the second time after seeing this kind of error.
that is really not necessary. you can finish the entire game in <2 minutes if you fast forward through the dialog. and there are no branching decisions, fail states or game overs.please share the save file from the end of v0.2
