I was struggling about proper difficulty before releasing the game, as initially I played it even in GOD mode and it was fun, but then I chose more hardcore approach and it was fun for me too. So I didn't knew what to choose but decided that a challenging gameplay will be more interesting for players. But perhaps I was wrong.
So here's the EASY MODE which you can set for the game at the very beginning. I hope it will help some players to enjoy the game.
