itch.io

sorry, but i agree with the other person and some on the forums. not everyone has the means to periodically authenticate their games, it's also bad for longevity. I can still play my playstation discs from childhood, but in 20 years your servers aren't going to stay up.

you can get a refund on steam and rebuy here, i did the exact same as you. 14 days after purchase and less than 2 hours played.
