Hi there! Game dev here -- I've noticed a handful of my games popping up on speedrun.com, which has been great fun to see. I've been in touch with a few of these communities and have added some quality-of-life improvements to make the runners' lives easier.
Unfortunately there's no way for me to actually tell when any of this happens besides literally searching for every single one of my games across the site to see if someone has already created a community for it.
This is perhaps more applicable to indie releases than anything else, but if games could be searched for by developer that would make my life a bit easier. Plus, you know, supporting the actual developers of the games we love, always a good thing ;)
The pipe dream for me is to actually be notified whenever there is a new game listed that's tagged with my name on it, but even just a searchable field would be good enough.
We used to have a way to filter games by developers (as well as publishers, engines, and "genres"), but there were a lot of issues with that system (both technical and organizational, and IMO were just not particularly useful in the state they were in) so those were dropped when Games/Series pages were overhauled a while ago. I imagine we'll reintroduce that functionality at some point in the future, but a lot of ground work needs to be done first if we don't want to run into the same problems we had with it before.
