Thank you very much friend.
Unfortunately im not able to update any game info now because im travelling and forgot the battery charger of my laptop. But hopefuly will be able to do this next week.
Im new with this Google play and ranks thing.. I only managed to get this amount of installs because of the huge media coverage. Do you have any tip to rank highter? What kind of icon should I do?
You actually did better than most developers including me. Honestly the googleplay store is so flooded that all you can do is hope to get lucky and get media coverage. Other than that you can
1) Post in android game facebook groups
2)Android game forums like xda developers
3) Post in googleplus community's (android games of course)
4) Post on reddit
5)Make various youtube video's that helps with the luck factor alot.
And the biggest secret of all only do this if your game is really good.
Do a pay per install campaign you need enough money to get your game ranked high enough so people can see it on the charts. So you would need enough to buy around 2,000-5,000 installs so you climb up the charts quickly. Thats probably the biggest secret I know of.
