You can always download it and then immediately uninstall the EGS app if you hate it but it's worth it for this game
It's got gorgeous art and incredible music and surreal writing and a cast with plenty of interesting queer characters and you can romance a bat and get a third eye installed and assassinate a sun
You can use Heroic Games Launcher to play EGS games without installing their app. It can even be used to play them on Steam Deck.
