You found a really cool idea ! When i was a kid i played games like diner dash so i understood the premise pretty quick :D Its a shame that you couldnt add more minigames but i think you have learned a lot from this project. Like other comments say i did not get what to do in the minigame :d.
Overall i think it has potential to be a great game you should work on this after the jam to see what you can achive :D
Note : I would be happy if you could play my game as well :d
