I haven't played Overcooked, so I can't say how your game compares to it. But your game has some promising mechanics from what I've explored (you can chop and fry the food to give to customers) but those mechanics (1) aren't explained in-game and (2) more importantly, aren't used at all. I understand the game's unfinished, but why have these mechanics if they won't be used? Perhaps cut out the kitchen entirely until it can be used in the game.
As for the the mechanics that are used . . . ehhhhhh. You can take a fish, carrot, or apple to feed to a customer who wants a fish, carrot, or apple (it seems to be random which food they want). I kept running into a glitch with the apple box-thing: when I pressed x to take an apple and walked right to go to the customer, I also took a carrot, holding both, and couldn't feed the customer. I also kept running into a glitch where I would drop the food through the customer instead of feeding it to them. Also, when I had 2 foods in my hand, I would drop the apple on the side, but I couldn't pick it up later--I had a pile of apples next to the customers when I closed the game.
Overall, I'm not too fond of this game. I did the same three things over and over, and didn't find it fun. I was hoping for more depth--heck, maybe a win/lose state, or a timer, something like that. But personally I found playing this to be rather boring.
