This is a really cute game, I like that the orders came from a butterfly.
I feel like part of the challenge is remembering the order and getting as close as you can, but it didn't feel so great to have to drag each ingredient one at a time. Maybe it would be good to choose an ingredient, and then click on the pizza to add one per click.
If you're going to improve on this, I'd find some nice meaty sounds! It would make it really fun to add items to the pizza if they each had a good sound.
Awesome job!
