Hi David,
have you tried posting a link to your game on www.reddit.com/r/playmygame ? It's a sub where you can present your game to other players and discuss it with them, but your game must be playable for free, and, as always on reddit, read the rules before posting. Hope it helps.
I have yes, here it is: https://www.reddit.com/r/playmygame/comments/9vtpwt/botsumo_a_local_2player_game...
An upvote would be appreciated, if it's not too cheeky to ask :-D
It doesn't look like you can add images or screenshots on that thread though, which is a shame because it's difficult to stand out
