Pretty good game! Some notes:
The visuals are.. Technically good looking, but in my opinion they don’t really have any charm or substance to them. I made a rough poster loosely based off yours, it took about 10 or 15 minutes to make. And in my opinion it’s a lot more visually pleasing than the one the AI you used generated.
If you want to get better at graphics: I highly recommend watching this tutorial!
But besides that: The actual gameplay!
I really like how you can combine the food to make new, unique meals, just a shame that so many combinations defaulted to the hodgepodge. (Potential dish ideas: Egg-mushroom-tomato, “Gourmet omelette”, lemon milk sugar “Lemon smoothie”, etc…)
Also, in the future: You could possibly add a way for the monster to get stronger, after winning, like if you beat the monster once, then the time to beat it goes down faster, or its health increases.
But I digress, you did really well for a first game! Especially given the three day time limit. I hope to see you improve!
In conclusion: Pretty bad graphics, fun to combine ingredients for dishes, consider adding progression by making the game harder gradually.
