Hey @s1ddok, thank for your comment! I've put a lot of effort in this game, but unfortunately it seems like indie times are over, at lease in my experience.
First when I released the app on 9th of January (Free + IAP) I had about 500 downloads, due to the fact that I spent a lot of money on ads + some house ads from my other apps. Then I made the game paid ($1.99) and had 1 or no downloads per day. It's sad... So now I made it free for a limited period of time..
P.S.: please rate it if you enjoy it!
