You have a README which is great, but you'll need a License file as well (these are two main criteria for open source category). Make sure you add a heading/title to your README. You can also add some screenshots to break up the text a little.
Loving the artwork style on this game; well done on utilising AI for it. I like the narrative you've built up and the sound effects on the buttons are a nice touch. Add some music at the start too to draw the player in more; I like the music going once the game started, super chill vibes and lovely.
Cozy game, chill vibes, fits nicely with the theme, and I'm enjoying it a lot. Maybe at the start where do the tutorial, say something like "explore each of the areas before spending all your moves". Ie. I went straight to the garden and walked around and immediately used up all my moves, lols. Slight glitch on the garden where sometimes I needed to press the move button more than once to actually get moving. It'd also be great if you could hover over things and the item would tell you what it does; ie. hover over the sword before making it and it'll tell you increase health or something.
Great job on your submission.
