First and foremost: Great game, stupidly fun.
Made it to day 9 with a score of 3380 points on my first attempt, so I think I've seen what the game has to offer.
It captures the spirit of an overcooked-like frantic management game perfectly, and I thoroughly enjoyed it. At the time of writing this, this is definitely my favorite game of the jam, and it'll be hard to dethrone it.
Some minor nitpicking, cause we can't go without that ;)
The sun's reflection made it so the item on my counter at the very right wasn't visible at the start of the game (also sometimes in the midst of play). I did quickly figure out that that item had to be a triangle, but it's just a minor detail that can be improved.
Sometimes it seemed that customers approached my shop with a little more than half their patience left. I am not sure if that's because they were waiting in line already, or what caused that.
I've also tried to look out for that in particular, and sometimes people waiting in the back of the line still come up to the counter with full patience. So I am really not sure why exactly that happened.
Sometimes people queued up behind other people, that weren't even at the shop yet. I can definitely see why that happened from a programmer's POV, but it's a minor thing that can be improved.
Sometimes people also walked a full circle around their goal position in front of the shop, which seemed like a funny little bug to me :D
If the player moves the mouse towards the bottom and top edge of the screen, the camera starts moving. Seems like a remnant of a feature that isn't used anymore, and thus confuses more than helps.
The endless mode of the game sadly becomes impossible once you don't start the game with enough water, because once you have to do smth else than serving the customers, you pass out of thirst. So maybe giving the player some extra water to help after passing out would be a good addition!
But all nitpicking aside: An amazing entry for a wonderful jam. 4.5/5.
