Hi zTribalx,
Yes, you will be able to access the game on Steam, even in countries blocked due to government bans (Germany, China).
As Steam automatically blocks access to these games for some countries, we decided to make Steam Keys available through Patreon, so anyone from one of these countries will still be able to access them.
You will also get access to an Itch Key, which you can access the game from here.
The Itch and Steam versions have the same content, with only a few Steam-specific features different, such as achievements that count towards your Steam score, portability to the Steam Deck and the possibility of playing using Gamepads.
We hope you have fun! :)
