Don't forget AdvJam where most games (it's a competition to make small point & click games in 2 weeks) are played and put on YouTube. To find these on YouTube, for entries in say 2018, AdvJam2018 should find a list of videos.
Once (2001) gave Brian Eno a demo CD at an interview. He cautioned "I can't promise anything". I don't know if he ever heard it, but it was a cool moment anyway.
Don't forget AdvJam 2018 (or other years) which have dozens of small games that actually are excellent. Favourite game is Spy Quest which emulates Sierra games of old. You can get AdvJam walkthrough videos on YouTube.
