Overview[]
This hack contains one level available to play in two difficulties called "baby" and "gamer". The level consists of a road stretching off into the darkness with a Swoop enemies (bats).
Mario is free to jump and move from side to side, but he will continually run down the road into the darkness. The Swoop's are travelling in the opposite direction; if they touch Mario, they will instantly deal damage that varies depending on difficulty.
While playing on "baby" difficulty, each Swoop will deal 2 points of damage to Mario; there is no way to recover HP. While playing on "gamer" difficulty, touching a Swoop will instantly kill Mario.
While in the level, the camera cannot be manually adjusted, and instead is fixed to a pre-determined path. The longer the player lasts in the level, the more wild the camera movements are, with it often changing angles, and even distorting the view by stretching and compressing the image.
