Its hard for gamers who didn't grow up playing that kind of game. If you played a lot of Contra games or Megaman, Cuphead is pretty similar to that kind of gameplay. Everyone is comparing it to Dark Souls because its tough. But its not tough because theres enemies that are way stronger than you, if you die its because you made a mistake. I'm not trying to say it isn't hard, it took me 10 minuets to get through the first level and probably close to 20 deaths. It really is one of thoes games you have to git gud at. You cant just grind skeletons till you're over leveled for the boss.
