I'd suggest on twitch, or optionally on youtube or discord with camming and streaming a lets-play could work, nebula49dev? Maybe adding an itch-playlist, marked as 'viewable for public' & checkbox to get it visible to your profile. Or adding a link to your dev's social-media blogs, etc.
Also I could offer testing it, in case it works as browsergame, being for free and my browser wouldnt lag when loading its graphics. I'm offering testing, translation from english to german language, finding bugs/typos, etc. while maybe different language-sections for your games, could get players prefer it because it's available not just in one language only. I've seen a e.g. spanish game, which wasn't translated but I don't understand it so couldn't offer translating it not even started it because of the description and title being in a different language.
Your game's tags and keywords could help players find your game. Same for choosing a creative title or bannerpic, possible screenshots.
