This is an interesting Overcooked-esque game. It's a surprise that you've managed to pull this much stuff off in 7 days! The pixel art graphics are very nice, and it seems like you got a pretty good gameplay loop going too! Nice one!
For some criticism, I'd say the difficulty and balancing really need a bit of tuning. Given the large size of the kitchen, the relatively slow walking speed of the chef, the amount of time needed for each interaction and such, I think it's way too tight if not impossible to complete every order. The worst offender I think is the dishes, as you can only take one dish at a time. This means it's essentially one more step for each order. The customers come in quite quickly too, and I think in my runs, it takes only the time for about one firefighting action until another customer spawns. That's just too quick. One last thing is that it's very easy to be not in the correct position to perform the action, or the inputs not being detected. It really hurts the game a lot when the core controls are not entirely reliable, and it will cause frustration in this already chaotic game.
Anyway, this is still a nice entry! Keep up the good work!
