Thanks for the additional info. I'm the one that uploaded this. I had a feeling there was probably an Asian repository where this was located. I checked out the other halloween maps I have. Info about them below based on the versions I have, which may be outdated.
halloween_construction: Appears to be complete and is pretty cool. I can't tell if it's actually complete as the final door requires 2 buttons to be pressed simultaneously. NoClipping indicates there are no other parts of the map, so the dual buttons must end the map, even though I wish there was more.
halloween_cemetery: Finished. Pretty short and straight forward, but at least complete.
halloween_inquisitor_a: Very unfinished. Just one small area and nothing is textured.
halloween_blackwoods: Very unfinished. Just one small area and nothing is textured.
I'll get around to uploading Construction and Cemetery. No point on the other ones.
