Maybe a decent presentation video would help. The video of you playing the game, is that how most people do it? I don’t want to sound like I’m knocking what you’ve done, but I’m just trying to imagine some kind of trailer for a AAA game where it’s a video of somebody’s phone shot in a darkened room.
Sure, nobody is selling AAA titles here and nobody has the same budgets as Ubisoft or EA, for example, but there’s no reason not to give it everything you’ve got. Can you add a live preview? Maybe you can export video from whatever software you make the games in? Add a nice background, some sound effects, a bit of music, text explaining features and creative editing… get people excited to play the game, plant the seed of what people can do with it etc etc.
That’s the way I see it anyway. But I’m no game maker. And I see that one of the top sellers is a racing game, so it’s probably not the item itself that is putting people off.
