Okay, that was really fun gameplay, visuals are really cool. Didn't see much of the theme tho.
Here's some feedback:
1. Pause is broken. Any order can be executed in 3 seconds cause you allow to switch between screen while in pause AND you see orders/ingredients while in pause. You can just endlessly plan your mouse movement and see what you need to do and it is just really easy to win. I managed to double quota without trying.
2. It would be cool if dialogs changed based on time which you spent making order. For example "aggressive" guy that always says that you're too slow said, that "you finally become a little faster than a snail" after you finish his order in less than 5 seconds. Or sleepy guy fell asleep if you took longer than 15-20 seconds for his order. Stuff like this will make reading dialogs much more interesting and less repetitive.
3. Add background music! It has so much impact, even if music isn't made specifically for your game and you just found it on the internet.
Overall it's really polished game that I enjoyed playing for around 10 minutes, which is cool for 48 hours game.
Great effort & good luck with your future projects!
