honest question: why dont you do steam
I dislike the fact that my purchases are controlled by a third party (example Steam) and that I do not own my purchases... that in fact it is only rental or long term lease. Plus I don't like being spied upon by steam or anyone else for that matter. My private time is my private time and no one else gets a say in how I choose to use it.
The dev can can at anytime decide that they do not want to continue to allow you access and pull the plug.
This has been proved by the Karens at "collective shout", they decided you can't play whatever game, for whatever reason, then informs the Credit card companies and steam has no choice but to pull the plug. That's why I prefer to use Gog, itch.io or any other non steam seller.
I own the game can install and play without big brother.
I only use steam if I really have to say there is something I want to try that is steam exclusive.. It's very rare.
ps: Love the game it's a blast
