Line Rider was (is) such a great avenue for artistic and tinkering spirit. Someone else here called it a "demoscene" and that's a perfect comparison. It's a very easy game and community to get sucked into.
This track is pretty cool, and that ending is incredible. Nice to read that you were able to come back to a revived community and finish the project. I guess I'll go watch all my favorite tracks now, thanks :)
As an aside, it's great to see many here on HN who also love(d) this game. Not that I'm surprised the two communities would overlap, but there were at least a few years between the last time I built a track and the first time I came to HN. There are such strong common threads of interest across the internet.
