What do you mean? Language? Difficulty? We have 2 supported languages (English and Russian), and in release version we plan to add more easier difficulty level)
Oh sorry, I can't tell those two apart.
Anyways, when I boot up the game everything is russian and I can't seem to find any option to revert that.
I wanted to play and noticed it was in russian as well. It seems to be in russian by default when you download using itch.io client launcher. What you need to do is right click the launch button then choose "show local files". Open the rooMaze folder and DELETE the app shortcut named "rooMaze.ru". Hopefully this helps you or anyone having these problems.
For the game creator: Possibly add a toggle in-game to switch between the languages? Or prompt the player to choose what language they want for the first launch.
