Man Cuphead was such a labor of love. It took so many years and so much effort to completely hand-draw everything, I wish there were more games like it. The game itself existing is a total miracle not just for gaming but in 2D animation in general. I think the developers made a really solid move making the game so challenging, games like it and Dark Souls getting a rep for being hard gave them so much more attention than if they were easier, it makes people want to check it out to see how they do.
