Yeah, I really agree with the difficulty in the game, I and a friend tested it out I can play the game in the casual level but my friend in the first place doesn't, I tested the game a million time that's why I can play it without any problem. And yeah I want the game to be really challenging, and I just notice how hard the game is for the beginner in the final day, I wanted to make difficulty level based on how kill the player had gained, but I didn't make it in time. Thank you for giving me a honest feedback! :D
