Ludum Dare's voting system seems good for this: the more you play, the higher your game appears in the listings! I understand that itch isn't designed for this, but hopefully you get a bunch of ratings soon.

Rated! Try mine if you have time? https://fniss.itch.io/ettin-bffs

Hi! I will play and rate your games! 

My game name is Room. 

It's a desktop puzzle game where you need to use the clues from the computer to escape the room. You got only one chance to do this. If u fail solving the puzzle the first and only time... The application won't open again.
