All of a sudden, I got a huge spike in Romania, Saudi Arabia, and the UK. I went from averaging about 5 users per day (mostly in the USA), to averaging closer to 20, with most of that due to those three countries. And for whatever reason, the new users have been almost exclusively on Android.
Unfortunately, I haven't been successful in holding onto players, and I definitely haven't managed to monetize much. Players drop off quick after the first level of the game, with only about 10% of players continuing after that.
So, of course, a very small percentage of players are even getting to the point where the game asks for an upgrade (in the last month, only 3 have reached it, and none have purchased).
Social Sessions also gives you the opportunity to watch an ad in exchange for a free hint on how to beat a level. This feature has not been widely used either.
So, as I said, it's been interesting. I seem to have tapped into a fountain of downloaders who don't really end up liking the game, almost immediate. I had a much more gradual dropoff of users, relatively, when I was only getting 5 or so downloads a day.
It's possible that there's something off-putting about the first level. Maybe it's so easy that players don't think the game is going to be challenging. Maybe they see the suggestion to watch an ad and flee. Maybe the pace is too slow. Or maybe because the tutorial that appears on level 1 isn't localized into anything but English, and so users just exit (although I tried to make it as self-explanatory as possible).
I'm not sure, so I'm putting some extra thought into it right now. If you've got any suggestions, feel free to leave a comment.
