World -2 is the name that is given to the glitch level in Chapter 2. It is unlocked by reaching a glitched Bandage Girl in one of The Hospital levels (You have to beat C.H.A.D. to get a glitched Bandage Girl). The style of the level is the same as World -1 but it is a house with less saws and involves blood lakes with fans. Since it is not the same level as World -1, it does not involve using the same strategy. And since it involves fans, it focuses more on jumping than timing.
