That is the unofficial china version of the mobile version.
This is the original unofficial (initially approved by jason rohrer but not anymore due to the china version first release being free to play and was possibly planned to be a free trial but isn’t really just a small “trial” depending if you consider trial a length of time for which it’s avalible for download compared to the limitability of the trial. If the game gets updated then everyone who got it for free wont be able to update it and continue to play for free. Please let me know if this is correct @Christoffer ) ohol mobile version.
