Anything simple can work for you. Advertising a little “sneak peak” of the game, what you can expect to do in the game or a feature you’re really proud of having in your game can be the way to go. Alternatively use sponsorships so your game appears as players browse game sorts.
Sure, if that’s what you like. The point of an advertisement is to look enticing and invite users to click on the ad to find out more about what you’re trying to give them or to poke at their curiosity. Curiosity is a powerful thing and being able to get players curious about your game can help in adverts.
i do upload videos of my game on my youtube channel, but i dont really put the video into my thumbnails since im not sure if i should spend 500 robux on one thing
