This mod is a house with some simlilarity to the alpha 2 build, but with new places and puzzles, as well as a hole new enviroment and surrounds. The Neighbor itself hasn't changed in a bit, neither the objects or mechanics, the only big changes are his house and the basement, witch sadly leads to just nothing, maybe in future projects i'll add a hole new place and a maze-like thing to it
Do you mean Alpha 1?
well, the first floor is just like in alpha 2, but with some changes. The rest is all kinda new
