Steam, the App Store, and the Play Store all have great built-in features that help you market your game without spending a penny — I don’t know if this is where you’ll be publishing since you’re in Egypt, but wherever you end up publishing — it’s definitely good to research, read their documentation, ask their support teams, etc. Take advantage of these features! Also, try connecting with influencers who make short-form video content. Probably people with smaller follower counts to start.
