Okay, in Mystery of Solarus, that Zelda game some guy made a whole engine for? Dungeon 4 is impossible. There's only one chest left, which by process of elimination has the boss key. But reaching it is physically impossible because there's literally nowhere to stand to reach it with the hookshot, you can only zip right past it. Then there's some cryptic shit about crossing four chests, I've bombed that area over and over and nothing happened. So yeah, the dungeon's unwinnable. If it is possible… Well, this is the kind of shit that belongs in a kaizo Baba is You level pack, not Zelda!
