What the?
What did you expect? Instant fame? You published 3 days ago. Itch does not promote your game for you. It does not work this way. Internal promotion on Itch itself just does not happen. There is about one place where you are allowed to promote your game and that is meant to promote it once and views on that post are < 100. Often < 20. And that's only people that read the post. Not people visiting the game. Passive discovery on Itch happens via tags.
/games/last-7-days this is 5000 games. Why should I play your game? Or even see your game at all? There is a new game every 2-3 minutes published. How many of those will go "viral" or get any kind of attention to boost them to high places in a popularity ranking at least for a few days? /games/top-rated/last-7-days less than 10% and you do not know how many of those were previously famous or did advertisement.
/board/10021/devlogs is a deprecated section of the message boards. It got replaced by /devlogs
Your game is 3 days old. What kind of development diary would you even have to tell. And why would anyone care and specifically want to read you talking about your game.
