A non tool assisted run of Umihara Kawase.
I never heard of the game until Retro Gamer decided to put it in their SNES top 10. Now I understand why they included it. A wonderfully humourous and genuinely challenging game. That little girl with the grappling hook is so funny!
(The game is much longer than it seems in this video. The guy used some level warps)
