However, players must find a way to traverse the room without being caught. Additionally, one of the rooms on the second floor is flooded and guarded by a robotic shark. The house has three floors which now has an elevator that the Neighbor uses to navigate between floors. However, the Neighbor’s house is now multi-colored and has a rollercoaster-like track wrapping around the entire building, with a tram car that is not accessible. In the Alpha 1 build, there are some noticeable design changes. However, Minor tweaks can also be found in gameplay with a few changes to the AI sequence of events. This version would introduce some new features both in the environment, actions, and sounds. Hello Neighbor Alpha 1 is the first of the Alpha builds and was released shortly after the initial Pre Alpha build.
