What if the game had a sound effect where if you overcook the food, a sound effect of Gordon Ramsay blasts in and says "IT'S RAW" XD
Overall, the premise was super cool! I think you could've definitely refined it further if you had more time, but you also made a lot of assets yourself, especially as a solo dev as it seems like, so lots of kudos to you! Here's some detailed analysis points that I have personally...
Creativity
The idea of managing multiple different pans at a time with different timers is a very unique mechanic, along with the timing mechanic required to successfully flip the pan! I think the idea of also having food and water to manage was also really cool, especially if you're trying to manage the pans at the same time. Using the cooking mechanics to manage a kitchen-like atmosphere could also be really cool. I think some cool ideas that you could try out is to have specific recipes and step-by-step processes to make specific foods. For example, if you are trying to make a soup, you first have to cook the mushroom, then use water, then flip the pan. Experimenting with different types of pans that you get from upgrading your pans and having longer timers on them could also be really cool!
Enjoyment
If you do decide to come back to this game, I would love to see how it evolves because the mechanics of managing different pans along with different ingredients at the same time could be refined further to make a great game! I think you could really push the multi-tasking a lot with this type of game, and for players like me who love the timer pressure of these games, you could really push for an experience that is slower for casuals and faster for competitive people. What if you did an esport on this LMAO that would be pretty funny.
Narrative
I see that you have a nice cozy background for your game - maybe you could make it like a spice-of-life anime where you could have your protagonist managing a restaurant in a highly competitive, esports dominated city, or a romance story where you are cooking up something for your partner. I would love to hear what your favorite stories are in media and maybe you could take some inspiration from them, especially the cozy ones. Maybe you could have a competitive gameplay experience with a casual, cozy story
Artwork
Considering you're a solo dev and you made all the assets yourself, that's very impressive! All of the items, pans, and water look really cool, especially the animation of the water cup! I'm very impressed you managed to make that all yourself - not that many people can do that all by themselves. If you were to just have a little more time, I think you could very easily make a unique art style that is yours that no one else can copy!
Audio
Depending on the tone of the game, maybe you could have a lot of goofy sound effects when the pans explode, like the Roblox explosion sound XD or like a cozy sounding water faucet dripping from the dispenser - you just have to decide what kind of tone you want for the game. Do you want to make something more serious, cozy, relaxing? It's up to you!
Overall, with the abilities you have as a solo dev, I think you can have a much better shot at next year now that you have learned more on this experience! Keep it up, your art style is awesome for one person!
