What happened to "Seery arts and crafts" YouTube channel?

It's been 2 years so a bit of a refresher: These folks made a series of paper craft animation videos about a continuation of HL2Ep2's story, Here's a playlist. It was exciting, very high quality production, but as suddenly as they started they stopped all production.

Anyone has, or still in, contact with them? I'd be great to get some words out from them as to why production fell apart, and if they would take feedback, support, and whatnot. I want to see more Paper HL3.

edit: Found their subreddit it's just as dead: /r/PaperHalfLife3/
Also rewatching the last ep they published it kinda feels quite telling that they aren't super hyped into continuing the series. Gordon is still in that hangar. :'(

The last episode they released (Ep5) had in my opinion both hints at how they didn't want to continue the series but at the same time how they still had some ideas on their story board... both to do with G-man.

A lot has happened the past 2 years. Epistle 3 came out and that would have provided the team with fresh new direction for the story line. If that alone is what is holding them back, then they would have continued with the series. Money should be no problem as they have Patreon. Even the Monster non-sponsorship of Ep5 would not be that of an issue (in case they faced legal actions) as they could have retracted and remade ep5 without it.

Thus I think the team simply broke up for one reason or another.
