There's a lot of hard work to be done Here's a list of things to do:
*Contact reviewers - make them notice it. If they like it, there's a chance they will write about it.
*Contact youtubers - have them try your game, if you're lucky they might make a video about it.
*Go to events and other gatherings, promote your game.
*Make a lot of promo/press material. Post it or send it to relevant places.
*Contact local magazine in your area. Send them a press release, maybe your local newspaper want to talk about a small new studio in town.
*Make gameplay videos.
And like A0Nasser said. If you're games are not unique enough they might never get noticed. There's an endless amount of clones so push the things that makes your game unique.
