Watched the whole thing, and maybe it was just due to the way the number of items from each year was distributed, but it felt as though a lot of the characteristics that make up your work came suddenly, in the past few years (at least character-wise; I saw hints of the way you do backgrounds in some of the 2012 shots).
Regarding the movie itself, 2011 and 2012 took up such big chunks of the runtime, it felt like those best represent the mood of the whole thing, which the tags really do reflect well. The soundtrack made the whole thing so surreal; the quick, jittery, snapshot nature of the way the animations were shown felt like I was watching a few "frames" from every dream a person had in a lifetime. A little wondrous, a little sad, a little existential, and all strange.
Aside from that, there were two major things that came to mind while I watched: the method of archiving/retrieval, and archiving in general.
Regarding the former, I'm curious, were these originally hand-drawn and scanned in to a computer, or done via Flash? I'm assuming the former, due to the bizarre way most of the images here to seem to have this jitter where they'll flip back and forth between different scales as if there was a scanning error. It would explain the timing, too; I was disappointed that 95% of what's here is timed so quickly that there's no way to understand what's going on unless you pause and keep re-watching. With how much is here, though, I understand why you might not want to re-time things, though. It could take months, even years, to get through everything here.
For the latter, it got me thinking about extreme archival in general. I've been doing a lot of digital cleaning the past few months with the quarantine going on, between 6 year old bookmarks I haven't seen in ages, ancient files from old laptops, and so on, and seeing what I can preserve and what doesn't matter anymore. It's a strange task, like an exercise in learning to let go. It's as if I'm afraid to lose the things that once gave me little sparks of joy, but if there's so much that it feels overwhelming, it gets to the point where the stuff owns me, instead of me owning the stuff. I bring it up because I get the vibe that your art means a lot to you, and with so much content in this video, I imagine you took every single thing you still had from all those years back, and uploaded it into one place. This probably is getting pretty ramble-y, but what I'm getting at is that it must feel good to have everything in one nice, organized archive that you can look back on.
