Thank you very much for playing our game. You are right. This game is very challenging. When I designed these levels, the original version was actually more difficult than it is now, so even as a developer, it is difficult for us to make it, so we constantly simplified the levels, optimized the difficulty and made it easier. I don't know whether the difficulty is suitable for you now, whether it will be too difficult or too simple. I hope to hear your feedback, which is very important to us. Thank you again for playing our game.
