This is super cool but I have a little bit of critique. I don't know if these things are intentional so please feel free to ignore.
Firstly, there's an exploit with Lettuce seeds. They cost 0 each to buy, but can be sold for 5g each. When I realised that, I just bought 99 and then sold them all for 495g - rinse and repeat and I'm rich to the point money is no object, which eliminates any challenge.
You've left your RPG Maker Project unlocked, so I was able to dig through - hope you don't mind but I've found some things. During my playthrough I could only ever get 1 cow, I assumed this was intentional but digging the code shows I should have got 2 - looks like there is a bug in the conditional branches.
I like the way that you've done the planting events, I assumed a third-party script but I prefer the way you've done it (though it does eliminate the need for the bed/sleep mechanic). The CG of Ava is cute.
All-in-all, good job!
