So I completed chapter 1 both ways (killed everyone and then without killing), but got no achievements. Is Galaxy failing to unlock them in this game for anyone else?

Same thing is happening to me. Completed several achievement criteria but didn't get the achievements. It's not stopping me from enjoying the game, but it would be nice to see a fix soon.

Achievements are failing to unlock for me as well.

Same here. Anyone out there who actually got the achievements?

Yes ...
I guess it's possible to unlock all achievements since ~2 months!?
But I'm not sure.

By the way:
If you've played already Aragami (finished some / all chapters, collected scrolls, etc.), you need to delete (or backup) your savegame (saveData.dat) to unlock the achievements. So, you need to play again ...

After Patch 1.06a your savegame is here:
%USERPROFILE%/AppData/LocalLow/Lince Works/Aragami/

Before Patch 1.06a the savegame is / was direct in your Aragami-installfolder.
You need to delete them both.

Have fun!

Thanks! They fixed the achievements a couple of months ago. I was missing the achievements for completing the first few chapters, but got them by installing the game on my laptop and playing them over again.

Hopefully, they'll add the level editor here soon!
