Twitch has one of the most engaged community of gamers out there. There are multiple organic and paid ways to promote your games, like partnering with streamers with a large following, or using their advertising solution.

Hard to not recommend Product Hunt Games since we're here. :) Lots of tech and gaming publications look at the front page for new products, so that could also be an indirect way to get PR.

Twitch is the best bet with a targeted campaign, but I think Reddit can also be an effective method with an AMA in one of the gaming sub-reddits.
