Help Identifying an Anime

EDIT: Found it!

*Hey, sorry if this should go into a big already existing thread. I went back 5 pages and didn't see any mega identification help thread. But if there is a more appropriate central thread, then can a mod please merge this?*

Guys I need some help identifying an anime. It's gonna require some real underground digging. Definitely no mainstream titles. This is full on indie experimentation.

There is a short film, animated by a Japanese fellow, which I saw on youtube probably around 4-6 years ago. It wouldn't qualify as anime for any of the major databases due to it being an independent project (if I recall correctly).

Description:

It was around 5-10 minutes in length. No dialogue--only a bit of screaming. Its about human-esque creatures who live like ants in big mounds with a big queen ant person. A giant monster thing breaks into their mound and kills them all. Then it zooms out and shows the earth from space. It's done in a sort of paper-cutout style. It reminded me of Fantastic Planet.

If anyone has any leads I would greatly appreciate them!


Edit: (didn't want to double post)

for a point of reference, it would be something like these: https://www.youtube.com/watch?v=4hHQfkjogxg

some home-brewed animation. It might've been a student short film though. I know I was able to search it, so there was romaji/English in the title (unless I searched the creator's account) but probably also some Japanese characters, and the creator's name is Japanese (that's why I would've been sure it was Japanese/"anime"). (I just thought to search "自作アニメ" on youtube, and there are loads of awesome looking indie shorts I'm gonna have to come back to once I'm finished searching for this one.)

I went through my youtube history but no luck. 1. not entirely sure if I saw it on my main account or a burner account, and 2. half the videos in my history have been deleted/removed and are dead links.

I think that I probably saw it at Catsuka (https://www.catsuka.com/), but that would've been like 5 years ago. I'm gonna make some help threads around some other places, but then I'm probably just gonna mine through those catsuka pages and see if I can dig it up.
