Cuphead is a classic run and gun action game heavily focused on boss battles. Inspired by cartoons of the 1930s, the visuals and audio are painstakingly created with the same techniques of the era, i.e. traditional hand drawn cel animation, watercolor backgrounds, and original jazz recordings.

After installing this game on Monday and being frustrated at the first level (fucking carrot), I gave the game another try today and beat that level and a much easier running level.
God this game is fun, I really recommend you guys try it out. You can always torrent it first to see if you like it.
The music and style is just too good. Have the OST on my phone now.
So far my best was a B though, have not gotten an A- or higher yet.
