Hello! First things first, I must say that while I do plan to add some localization to the game, I unfortunately have very little knowledge of Korean to make a decent translation for the game. Well, one that doesn't use machine translation.
You do have my permission to try it yourself though! Not only will I be thankful, but your name will be added to the credits of the game! :)
I would just recommend waiting for the next update, as it will be rather important. It should be coming out very soon though.
