Opinion Slot Machine Garden

I come to you for your opinion, and to know if it is justified.
I have been working for over two months, on a slot machine template, an example that shows players how to create a slot machine with a mini game. I posted my project as a developer on December 13, after two months of work, I only got an answer today, saying that my asset is refused because it is "too simple"

Asset store admin message :
"'Slot Machine Garden' has been declined.

This package is too simple for our current standards. Please spend more time researching the current game market, polishing and tweaking your package to a high degree of quality, and expand its contents to reach a broader audience. We recommend visiting the Asset Store Forums so users may give you more feedback: https://forum.unity.com/forums/assets-and-asset-store.32/"



I need your help. We are not all 2D / 3D professionals, nor do we all have the same free time to be able to invest as much as each other. But if we can at least share our knowledge is not there the spirit of a community?
I find the refusal unjustified. I accept all the criticisms but tell me that it is "too simple" no.

The player plays with a slot machine and can collect water to be able to grow vegetables which allow him to win the jackpots. I remember that it is a template.

As you can see, my work is anything but "simple" I invested a lot of time in it so I would need to have your opinions. I don't know if it comes from me.

Thank you for taking the time to read
Cordially
