So my game game isn't going to the top of new releases when it gets indexed? If so is there a way to do that? Like I said all the exposure helps even if it's a little.
Yes, as you've read in the FAQ, after a while you can try to make a devlog post. If itch.io staff approves it, your game will be placed back at the top of Most Recent. But giving your game exposure is up to you. Indexing is a convenience to players, not a marketing tool.
Yes, as explained in the same FAQ, you can promote the game yourself. That's the main way to speed things up. Being active in the community helps for example. But three days is a very short time, doubly so with a weekend in the middle.
