I've recently started to speed run VVVVVV, after playing the game for years and noticing my times would qualify on speedrun.com. I've been practicing on my route, trying to optimize it more to bring my time down. I'm aiming for sub 19, which would be top 100 as of writing.

There's still some optimizations to be made - Laboratory, Warp Zone and Tower are not clean, but I've hit PBs in both Intermission and Gravitron by around 30 seconds, which led me to beat my PB.
