This is such a nice concept. I could tell from the font that I was going to enjoy it! It had such a cartoony and fun feel.
The whole vibe of the environment was pretty cheery, with the music and sound effects, even when it got hectic trying to service all the customers.
I would say the biggest barrier was the AI routing. I was impressed that you had that implemented! It was a little buggy, though, which started to feel frustrating when customer satisfaction was on the line. I know that's a huge challenge, especially for a jam, so kudos for getting it even slightly working.
Overall, this felt like it could be a complete game. It had nearly everything, just needs some minor tweaks and polishing of the AI.
