This was quite a mixed bag. I admire how you all worked together. That's not something casual and requires good planning and communication, so well done!
I like coffee shop simulators and they're a good fit for a cozy autumn. The environment is pretty decent as well.
What I think doesn't fit so well are the among-us-like characters. I know humans are hard to model. But animals can be easier! For example, walking cats. But it's okay, for a game jam capsules are sufficient.
Then... the gameplay. I feel like it's not very inspired, it feels a lot like a Roblox game (without the microtransactions). Which isn't bad per se, but more creativity and thinking outside the box is always great. You don't have to reinvent the wheel and create an entirely new genre, you can begin by adding small tweaks to the gameplay that differentiate it from other games (maybe something fall related).
And the balance needs to be a bit better. When you don't have a waiter you will miss lots of customers no matter how fast you are. But when you have one then it's pretty easy.
But, I admit, many of these things are maybe not something for a game jam. I don't know how little time you had, as you said, maybe it really wasn't a lot. The friend that I worked on my project with often told me that I had too high expectations for a game in a game jam, even our own project, so don't think that I'm being rude haha, I'm trying to give feedback so y'all can improve! :)
Keep at it! I think you can definitely make this game better and more fun by working on it further after the jam :)
