Hello, dear DEV!
I fully complete game and i have a FUN and have some suggestion to you for this game, it okay if you don't gonna answer, but i think you gonna LOVE it!
1)Add some kinda system of craft, to add some decoratio for island, because he kinda look empty(BUT DON'T REPEAT A SITUATION LIKE WITH AI*Shoujo)
2)Add ability to hug Mia(i like hug from tall peoples...), and some tease from her, when she caught you in tag game(make her in moment of caught hug character like normal BUT MUCH TIGHTER to herself, please...)
3)fix rock(maybe make him just rectangle, because i see you tried to make hitbox more accurate, but because of this Mia just becaome a vegetable and just looking to this rock
4)add memes or references, for fun(you even can add meme to your own glitches or errors in game what you fix, just like Brawl Stars community even now just make memes of how Morty can ben able to go throuth walls)
5)add shop
6)add some fights(BOSS FIGTH WITH A SMALL SPIDER FOR NORMAL ROCK, BUT 25% GREENER)
