If your game comes up when searching for the full title, then everything is working as intended. A partial search however, e.g. for the word "space", is going to return a LOT of games, and yours will be lost among them. And to find it by a tag, use tag filtering, not the search box. Trouble is, you have a misspelled tag ("astroids"), and one that's nobody's going to look for because it's just your game's title ("treacherous-space"). It's best to select suggestions from the list when entering tags.

Thank you for your fast reply. I fixed the spelling of asteroids. But even when I typed in every single key word except the title of the game, the game did not come up. "2d action fast passed free retro science fiction space "space shooter" asteroids" even that and the game does not appear. It is not lost in the other games. I looked over every game that came up and my game was not one of them.
