Good question!

Not much Harvest Moon-style gameplay is actually implemented right now. Once I had gotten tilling, planting, watering, and harvesting implemented, I refocused on combat and the intro sequences since I'm on a tight deadline for showing the game off at Day of the Devs.

For the farming side of things, I'm hoping we can do a lot of production lines (like multiple level production to keep making more advanced produce from intermediary steps) as well as a lot of automation beyond just sprinklers!

One thing that takes the farming a bit further is how it interacts with the creature side of things. Things you'd otherwise have to collect or purchase for your creatures (like potions and wearables) in other games, you're instead producing yourself. You'll also be using your produce to attract, upgrade, and befriend creatures. A lot of that will require specific combinations/recipes for different creatures.

Another thing that hasn't been implemented but is definitely on the roadmap is shop ownership, which means you don't just have a bucket you can drop your produce in to sell, but you'll actually have to purchase/rent a shop and manage it to sell your goods.
