Cute and funny concept! Strong color palette consistent throughout all the art. Lovely custom UI and menus. It's always great to see a VN that doesn't just use the stock Ren'Py UI.
I like how sweet and wholesome the writing is. (The fish puns, like "Oh crab", got a couple laughs out of me) I also laughed when I realized what was going on with the love potion, that's very cute and a great hook.
I noticed the voices are a bit quiet compared to the music, especially Milio's voice. Also, during the potion making minigame, the notebook just has a list of ingreidents, but no info on what is crushable and what isn't. My tired-today butt missed whatever info on that was shared in dialogue so I ended up with a D in potion making 😅I also feel the intro is a bit wordy and could be made more concise.
But these are pretty minor issues. Great work on this game and best of luck with the full release!
