I dont know where you find this term "I own the whole graphics of the game" by copying I mean "Exactly like my my game" . I mentioned in a post that I used the graphics and created my own too from an open source. It's true you didnt mean any offense or disrespect, but the way you mentioned this it's like I am a thief and I didnt give proper credit.
Don't mean it like that, but all I'm saying is your game has been around for years, with those same graphics. Yes those graphics are free to use by anyone, just your saying others are copying your game with your graphics and your gameplay. Anyway as I said before I wish you well with your game. And it's good that it's doing well.
Absolutely a good looking game! How much time did it took you to develop it, with all updates and all?
i remember your game noticed by Buildbox team and they also shared it into their official fan page (fb). i am happy for you finally you made it Also yes constantly improvement- this is what google love. For the copycat well i think when some people start copying my game that means i am going to the right direction lol. best part of the process is, you did not give up! Tips Now you need to optimize your ads. use interstitial ads for chartboost and admob. makes priority to chartboost first then admob interstitial ad. Again Wish you good luck for more
