I've played many of the hello neighbor projects on scratch and they don't feel like hello neighbor, but I see their limitation.
I used griffpatch's 3D maze game and my ray skills, I'm able to create an AI that can somewhat imitate the neighbor's behavior in the early alphas. The neighbor cannot see through walls when approaching and wander without clipping into walls.
That's my best at trying to make hello neighbor on scratch.
