I think Twitch would be a great place. You can also DM (Direct Message) streamers and/or email them. Before you contact a streamer, see what content they post, if they post the content your game has, they are more likely to play your game. Email them individually, don't copy and paste an email to multiple streamers. Patience is needed, as streamers often get many emails and it could take a while for them to get yours. Also, make sure to proofread your email before you send it. If a streamer does not respond to your email, don't pester them, move on. Make to get to know the streamer first individually before you send them a thumbnail of your game. Make sure the thumbnail is intriguing, as it will be easier for a streamer to use an eye-catching thumbnail for the video they are doing about your game. Also, thank you for being willing to give feedback if I post a future game. Another thing, I would love to know some tips and tricks for Unity, as I see you use that engine as well. Thank you! One last thing, I have a post that for this question that I had been wondering https://itch.io/blog/988061/how-do-i-make-a-game-a-lot-of-people-will-appreciate
