We generally tell developers that the “most recent” page is a bad place to market your game. Maybe it might work for some lucky people, but that page has hundreds of pages going through it daily. Your update was 18 days ago, that’s ages ago in terms of time for the most recent page.
Making a “Major Update” devlog may cause a bump on your page in our algorithm, but there is no guarantee. Establish your game in our system with regular updates and collect players and your page will be recognized by our system and be more likely to receive bumps from activity on your page. We can not guarantee traffic for any particular single page or developer since we are a public publishing platform with thousands of new pages created per day.
I recommend prioritizing growing organic traffic through your network. You can also use a broad range of tags & classifications to ensure that people coming from many different pages are able to find your page. Think of the traffic that itch.io gives you as a bonus on top of your own promotional efforts, please do not have the expectation that itch.io is going to give you all your traffic. itch.io has nearly 1 million games all competing for a small number of slots on the top of pages like “Most popular”, “Most recent”, etc.
Hope that helps
