The Caverns of Hammerfest, a web browser platform game made by the same dev who did dead cells, it's a sort of mix between bubble bobble and TBoI (once you are dead you have to redo everything and you don't have all the items unlocked at the beginning, you need to do quest) where you are a cute snowman who fight to get his carrot back. The game have 103 main levels and around 200 optional levels called parralel dimensions , it's maybe one of the most difficult game i've ever play, some people play this game since 10 years and struggle a lot to the hardest and the longest dimension, the hell
It would be amazing to have new runners, this game is completely free here : hfest.net

I wish E.Z was more popular, its a tough game but makes for a super fun yet extremely hard speedrun. Loads of RNG, tough(er) skips and lots of quick reaction times probably dissuade people tho ;/
I wish that Sonic Riders was more popular because absolutely nobody know the existence of the Sonic Riders games...
https://www.speedrun.com/redfaction - I'm obviously biased, but Red Faction (1) is a great game, with a great community of speedrunners who are all constantly finding new skips, tricks, and strategies.
