Hey I played. I think this is an interesting concept. It would take a good amount of art and polish, but I think you could pull it off. Here some feedback notes I have:
-Some of the action boxes are too specific, like you have to stand in a very specific (and weird) spot to get the wood to chop. Same for the fire and cow.
-There was a bug with the dialog, where a previous one never cleared, and so I couldn't read anything after that (this was like the 3rd day)
-I ran into a lock on one play through with the idols. I think I picked them all up at once, or place one then picked up another before sleeping, then this locked me so I couldn't progress. I did it right the second time, though. Then I seem to have gotten locked right before the 10th day (!!!). Am I the first-born son? What was gonna happen! Maybe it's better I got locked.
-I like some of what you've done with the plagues already, and I imagine you can make it pretty epic
-I think you should brainstorm more clever ways for the chores to evolve based on the plagues. You've already got some of this, like with clearing the dead fish. But I feel like that could be really engaging. Like you've got this routine that you build up, but then subvert it in different ways because of the plagues. Like now all of the crops are eaten by locusts so collect dead locusts for us to eat. And it's dark now, so you have to cut more wood for the fire to get light. And if you could figure out a way for the player to get really attached to the cow, that could be an emotional story beat.
Anyway, just some thoughts. Like I said I think it could be an interesting concept. Good luck on continued development!
