I've made a freeware, co-op platformer a few years ago (back in 2015). Since I was already interested in speedrunning and played it a lot during playtest, I ended up learning and practicing running the game. The run can take from around 3.5 minutes (in the fastest route) to around 6 to 8 minutes (visiting every room and getting every collectible in the game).
I've considered submitting it here a few times, but I always feel like it's too much self-promotion, and I'm not too sure whether there's value in submitting runs that are already quite optimized (although I can still see some room for more optimizations).
What does the community think about a (hobbyist) game developer submitting their own game (and, then, their own run) to speedrun.com?
