Here are some games created using Godot that you can find on Steam: https://steamdb.info/tech/Engine/Godot/

If you prefer, there's also a collection of Godot games on Itch.io: https://itch.io/games/top-rated/made-with-godot

Personally, I highly recommend checking out Cruelty Squad: https://store.steampowered.com/app/1388770/Cruelty_Squad - It's a fun game with a unique art style.

Circling back late here, but thank you.. and thank you to all the sibling commenters as well!
