Thank you for trying out our game!
The knife is not supposed to work from the wood - the idea was that user is supposed to go to the upper layer and throw it on the knife :D
Thanks for reporting the bug.
About the water as first ingredient - we had a talk about this. Artists were telling me to add it to the book on the first page, however, I thought it would be obvious if we add the word soup in the main menu.
The arrow was moved after the screenshot was made. There’s indeed thin line between overflow and having enough water, however, it can be done without overflowing.
Thanks for the feedback!
