My next observations confirm that the best You can do and what You can have is good possition after Your game has moved from "best new" category to "best all" category. I mean paid games but I think it works for all.
Faster You reach first 5 places, better possition You will have after "new games" list.
WHen my game was on 1st place in it's category (casual best new paid) the numer of downloads was better day after day but it was only a few days which gives not good total downloads (250) at the end of the "new games list".
Now it is 90th possition in all casual paid games and it is not so easy to find it as before. Number of downloads is 4 to 5 Times less per day because of it. So in my opinion, very important is to use as good as possible the first month where the game is in the best new category (paid services probably are obligatory). Good is that it is still on the 5 to 10 downloads per day. and it is not bad for my paid and first publication. The next step is the big game update and new free trial version with ads (banners and review on 148 group and review booster maybe). Also the new game is coming but this time free with microtransaction model.
