Mmm, I don't think the time limit was necessary. Figuring out the recipes is quite fun, and it requires to be creative and experiment with a bit of everything. I liked that concept! But it took me a lot of attempts to finish everything in time, and eventually executing known steps as fast as possible was less interesting.
Also, it took me a while to find out that the plates must be served on the tables. Maybe it needs to be more highlighted?
The idea is still fun! As said, manipulating random objects to see how they transform is cool. I enjoyed that aspect of the game!
