After passing the "13h", I feel more like playing a clicker with fewer clicks.
The concept is nice but could be improved with a limit of 5 for each ingredient forcing the player to watch his stocks more frequently. It would also be good to penalize the fact that the player does not have more ingredients in stock to avoid waiting for 0 that the food becomes cheaper.
In spite of that, the game is rather nice for a game realized in 48h. Congratulations!
