It looks like the project is going well so far. Good job. The only thing that really stuck out like a sore thumb, that also makes me want to ask "Was it REALLY like that back then?" is the grapple. I was playing on your test server and noticed that the grapple is a sticky grapple - press once to enable, press again to disable. This seems a little odd, but if you are keeping it for the sake of nostalgia, then so be it. If this is the case, that it was like that back then, whoever changed it, made it way better by not using sticky grapple.
