I'm so excited that I can't wait for the iOS version to pass review (now approved) and I'm sharing this with you now
Here is my first ever game, which became more than an educational project for me:
Android: Lost Forest TD
iOS: Lost Forest TD
It is currently using cocos2d-x 3.13 + SDKBOX review, play and IAP plugins.
Thank you Cocos2d-x team!!!
