1. Download the game from game's page
2. Unarchive the archive using 7zip (https://www.7-zip.org/download.html) or Winrar
*make sure to extract everything, extracting just 1 file will give errors
*make sure to have enough space (at least 600 mb)
3b. [Android/Phone] Copy the desired .apk file to your phone and install it. I recommend starting with x64, if it has issues (visual or performance) try normal one (Orks Ryona BBC_itch.apk), if there are still issue then install the _Low.apk version.
