Very, very good! I like the artstyle and the chill music. The sacrifice transiton effect is very good. The level/map is simple but good. Almost full marks! Your only issue is that the GDD is not completed.
Everything I have below is suggestion and I don't rate on these:
I am not getting a cursed vibe- I'm more getting a vibe that predation of the anthro villager is happening, instead of what the text says. I think a few elements of "show, not tell" would help in adding a cursed atmosphere: maybe there's more trees around but the farther ones have cursed non-natural tree parts, like eyes or flesh or dark tendrils or even tentacles instead of branches.
I like how the villagers look tired, ramp that up in subtle ways to really sell the physical debuffs (example: less sanity = bags under eyes, maybe bloodshot, messy har)
Adding the villagers in certain sections of each "working" place, either visible as cards, perhaps even unique character animations working in the environment, would grant a very lived in feel.
Adding more names would be a good thing. I have had many beatrices and celestes.
BUG: when i recaped month 7, it didn't start the sacrifice choice, and had me replay the month. After doing that it worked as normal EXCEPT month 8 remembered who I placed for month 7, except the new villager card i gained from sacrifice.
