First attempt to sync something up to a line rider course. after 1:30 seconds I started to give up a bit, I had to shut down my computer unexpectedly and didn't think about saving, even though I had 5 more seconds left to make. I want to pick up better tricks than just flings and manuals but I don't feel the need to learn them for a meme-ish line rider course. I used lr.conundrumer.com for syncing and frame by frame manipulation. I didn't even realize the trigger points were an option I could've selected with that version until after I finished it.
