There's plenty of PC game's development goes.
Depending on how many stretch goals the game breaks, Harvest Days could get an in-game museum, an assortment of new minigames, a photo mode, a new type of pet, and the possibility of full online multiplayer is there, too. A father-son duo is making this one, so you might need to give those features a moment before they're ready for the game.
There's plenty of other goodies for backers, too. You can get a copy of the game on your platform of choice, in-game character skins, and a position in the game's credits. That's only naming a few of the rewards, too.
Harvest Days is set to release in full in late 2022, with a PC-only early access version planned for earlier in the year. You can catch the trailer below:
