im not too sure about this, but the block ability should maybe return
every neighbor would have it, and the block ability would make kids try to fight the neighbor less. if you hold the button for blocking, you will get slower and cant interact with things, cant jump, cant grab, cant pick up items, etc. the only thing you can do is crouch. he would do the animation similar to the animation from hn1 when you stun the neighbor, and you wont get stunned and will take damage when you get attacked, but much less until youre low hp, then you wont take any damage anymore (3 hp?) until healing again. a block ability would also allow for more abilities for the purpose of the neighbor not getting killed so often to not be added, which would also allow for more different abilites. theres also leftover voice lines for blocking, so it wouldnt be hard to inplement, and for guest you could just use some generic clicking sounds.
there might be better solutions to fix the kids grouping up and obliterating the neighbor, but i just came up with this.
