First off, congratulations for making a 3D game solo in a jam, I know how much more difficult it can be compared to 2D and this jam is my first 3D jam game as well (also solo).
As others have suggested, you need to look at the movement speed and the asset sizes. I also think you could refine the layout of the kitchen to make it feel a bit more intuitive. I have worked in a kitchen before and speed and consistency are everything. The layout of a kitchen, if done right, aims to reduce the amount of time spent going from point A to point B. For example, I would place your soup pot and your salad prep closer to the serving point. For any multi-stage processes, I would organise an outward/in approach where your first stage is furthest from the serving point, working towards the serving point.
Thanks for the game.
