I love the ambiance of this game! You have excellent sounds and pixel art, this game is cute and super charming.
The one thing I think this game needs right now is a little more clarity. Something to signpost the fish stall and the player house to set them apart from the other houses would be good. I had to redo day one 3 times because when I would get back to the house I'd be presented with the two options of main menu and retry. You have a good tutorial walking up to the fishing spot that does point out the stall to sell the fish, but when I had walked up to it the first time I didn't see a prompt or anything. Once I successfully sold my fish I was able to progress to day 2. The fishing mini game is tough to get down as well. I had a hard time keeping my eye on the fish and the bar to time correctly, but once I stopped trying to look and the fish and just listened for whether or not it was making the sound the game was much easier.
Excellent job, I'd love to see this expanded!
