This is an impressive amount of game to ship in the compo, great job. I second the "Remy plays Overcooked" vibe, it's great!
A couple little bits of feedback:
I had some trouble with the physics collision bits — at one point I had accidentally backed up a line out my door and was hopelessly in the weeds — my culinary rodentia were cooking and plating up a storm, but my legs could only carry me fast enough to keep one table fed at a time (the one nearest the door). I know a big part of the challenge in the game is that the chef's not exactly a speed demon, but I think he might benefit from being a little faster or having a little "dash" he can do to scoot around quicker (Overcooked is a great precedent to draw some inspiration from there!).
My first playthrough I didn't realize I needed to staff each station with a rat, so I wasted a bunch of time trying ot figure out how to do the cooking tasks myself. A little more aggressive tutorializing, or starting with a rat-in-hand or right on the sewer might help!
There's a couple spots where the colliders interact a little strangely with the player — when carrying a rat inside, you have to aim yourself juuuuuuust right to squeeze between the bottom left table and the wall.
All super minor things though, this is an excellent game and an impressive result for compo!
