This is easily one of the most wholesome jam games I've played in awhile. Don't tell others I said this, but in these 3-5 days, you've achieved what most people don't get to in a full 7 day jam. Dialogue, inventory, a shop, player progression, pets, and hints at some story/lore! Quite a bit to throw together, really nice work! You should be proud of yourself.
My only suggestion for next time would be to throw in some sort of "end game" or "end state"; this is where the player feels like they've finished the game. In this case, you could have had some dialogue at the beginning of the game, perhaps the player is reading a letter, saying something along the lines of "You need to earn 200g to save the farm, better get planting! See the shop keeper to pay the loan." And whenever they select that option you could show a "The End, you did it!" screen, etc.
Looking forward to your next title!
