Hi. Did you tried with sharing the game in these posts?

Also. Another user is trying to start a 'hub-like-channel' for devs and players to show or review their games. Perhaps you can make a video talking about your game and submit it there:

If not, you can try to search for small or new YT channels and contact them.
Lucks.
