Unfortunately, I don't thing the game is working right for me. No matter what I do, I don't seem to be able to give anything to the creature. No matter how much food or poison I bring, when I end the day and click "Feed", the hunger bar goes down and the rest stay the same.
Still, I'll say what I can about the rest. The idea of the game I think is really good. You don't know what's growing there, but you know you have to feed it if you don't want to be next, so you frantically search for food around. But, you also have the option to poison it and try to kill it (I'm guessing, couldn't try it.). All of this before nightfall. The premise is good.
The artwork fits the game really well. The pixelated little area looks cozy, which makes it contrast a lot with the creature shrieks. It has that uncanny feel to it, and I think it's really well achieved. I also like how as daylight goes down, it actually gets darker, though for some reason a lot of things are not affected by the light so they just look incredibly illuminated around the dark soil. One thing I would change is making the ambience sound effects a little louder. The wind, tree leaves rustling, the ocean, maybe some animals, etc. All this so that if you're away from the shed, it feels relaxed, but of course you have the creature in the shed. The false sense of calmness can be really spooky.
I'll keep trying to feed the creature for a while, or maybe you have some hints if I'm doing it wrong!
