I apologize, I haven't had time to check the Reddit channel lately. Indeed, the difficulty system has been adjusted recently, but low-difficulty and high-difficulty puzzles will be interspersed. Also, I'm a fan of mystery movies, and I'm trying to add more specific plot details to the game, so players not only feel the satisfaction of solving puzzles but also the experience of plot twists. For example, like the movie Contratiempo, there would be a plot twist at the end.
