The player is supposed to block the shadow from killing the Neighbor, getting slightly bigger each time. He climbs a staircase and the shadow breaks the house, the neighbor dies, and the level is reset.

He walks over to a cupboard, knocks over a vase, and gets scared as the shadow appears in one of the windows. One of which, called 'Final Thing' has the neighbor making child noises and playing with toy versions of his and the protagonist's cars. In the modding competition 'HelloMods' there are several unused ending maps. The ending shows the protagonist about to leave what seems to be his apartment, due to being evicted (judging by translation of the letter and in the E3 Beta Reveal ). The player must get to the door with a white glow inside it and overlayed by a shadow that vanishes upon approaching it. Here, the double jump ability is required to explore much of the basement. Instead of exploring the basement, a trigger sends the player to an ending where the house is brightly lit and the Neighbor is seen crying near the wall for unknown reasons.

The Basement Trailer shows there would have been a whole section involving running from the Neighbor and escaping. The basement is developed in this version, the protagonist manages to enter and explore a bit of it before it ends on a scare chord. Note that the Pre-Alpha has no ending, as there is no basement. Alpha 1's ending is mostly identical, but the basement door is unlocked, however the protagonist is once again caught and buried alive. The protagonist makes it into the basement in this version, but he was chased and hide in the closet and defeat giant neighbor by.
