Hey!
So first off, the art style is very pretty. It really gives off a very old school vibe, which I really like.
I think your game would benefit from two things:
1) I don't know if this is an issue on my end, but it seems like you made the viewport way too small in the WebGL version, to the point where text is cut off and I can't read instructions or find buttons. You can fix this by reviewing your viewport size, but also by setting your canvas in Unity to scale with the screen's height and width instead of using constant pixel size.
2) Some more player onboarding. Since I couldn't read the instructions, and most of the text was cut off for me, there's a lot of the game I feel I couldn't access. I think I killed a deer and talked to a farmer, but other than that I think I couldn't do much.
Very cool idea! Would love to see this expanded on and revisit it sometime.
