This seems like a fun idea, but after I made the pizza, I was completely stumped on how to actually deliver it. I tried playing it multiple times, thinking I had missed something, but I never spotted a button that says "deliver pizza" or anything like that, and letting the excruciatingly long timer run out didn't do anything either. I feel like I tried clicking everything I could, but nothing worked.
I must be missing something, but I feel like there's a chunk of the game that I can't even access (that other people could)...
