Really interesting! Technically, everything seemed super-smooth. I liked the teeth transition effect, the low-fi sprites and eerie music, and your own voice acting which isn't half bad!
I got momentarily puzzled by the various mechanics... till I saw the teeth hovering over a villager and realised what was up XD I imagine in a more fully realised version of the game, you'd introduce these things one at a time perhaps.
I see you even themed the GDD, nice touch! Great submission, well done.
