I was first taken aback a bit, by another "bring item to customer" game - but yours plays very different from the others I've played so far.
Going through a stealth section and picking items by just some keyword description is an interesting spin. It took me a couple of attempts to get, that the guys on the pews were actual obstacles. At the start I just tried to speak to everyone, getting I guess reprimanded by the cult leader again and again. (This part of the dialogue maybe should've been clearer in that it's a punishment you try to avoid)
I do think it's interesting thematically to increase the difficulty of the stealth section by the room filling up constantly.
Also really nice music and atmosphere.
