My only complaints are that there's no NPC cycling endless mode and no "doll" where you can experiment with different potion combinations without penalty. So basically a variation of "We want more" you already addressed in the post.
The game itself has a solid premise and aesthetic and I always enjoy these "papers please" style games.
There's one, I'm assuming, bug that I've noticed. The thief the scroll is for is shown to have the spanking curse if you use the curse identifier on her even before you use it on the jar. Not sure if this got patched in the update though.
