For one, the thumbnail of your game that appears in search is too wide: I see only "nwante" visitor. How about making the title a bit smaller with a bit of color/atmosphere around it. And why not upload a game play video, so we see how it's played? Also your tags are few and very generic: a tag like "top down shooter" or "unity" must generate thousands of results; try something more specific that generates less results (so that your game is visible in the search) and use all the tags you can have. How about a banner for your game page? Optimizing one's game page takes time, don't get discouraged too soon. All the best for your game!
