How does the game actually look like?
https://bitcointalk.org/index.php?topic=4139653.0The thread has a few screenshots from the game. It literally had 1 UI page. Where I asked for the BTC address from the user to where the payment should be sent to. There was nothing of Gamblish nature in the game. It was a faucet but in the form of a game. The reason specified in the email was of the payment method in my app. Unfortunately, I no longer have the email I received. I don't have the source code either. I am working on a similar project tho. I will give it a go again but I doubt anything has changed.
Anyway what you are thinking with a separate app store might be a good idea but the the thing is this will require a lot of resources just to develop a system where your app store eliminates "malicious" softwares
True, but I feel like there are solutions to this. One of them is listing what sorts of permission this app requires before installing, just like Google does it. Another could be submitting your code which will then be compiled into an APK on the blockchain, so it will eliminate many of the malicious apps off from the store.
