omg, its been years and itch still haven't implemented an 

Achievements system 

what are you guys doing ?  

I hope the management of this company realize that people actually would decide buying the game on steam just because for the steam achievements / trading cards , for those cute little icon & badge  ( me included that's why I haven't bought a single game on here I won't even bother to get it even if its free like epic game store throwing money giving out free games  ) 

people need achievements to get that sense of completion 

Gamerzilla is my open source game achievement system. Originally it was tied to Hubzilla but I recently created a standalone server in  .Net. Itch.io could integrate something like that into their site or simply have other sites run achievement servers. We just need game developers and game launchers to support the system. (Technically you don't need game launchers. I just find it easier to have login information in one place instead of adding it to every game.)

My current achievements are available on my test site.
