Simple enough idle game, it is literally great! I am speechless

There is no other thing to say about this game other than it is like reading a manhwa. The graphics and UI are good enemies are well, BLACK. Based on the title, though the mask is essential for your progress in the game and the weapons you acquire, need to upgrade or combine. You will be bombarded with rewards after the cutscene. Great games are definitely worth it, especially when you AFK and do something.
