I have tried your mvp and I must admit it look impressive for platform in a beta mode. The shop in your mvp only real hardware, since you said e-sport, I wish soon virtual item will be available. About task in your mvp there are only vk and twitter, why there is no facebook? Most of my friends who play e-sport are using facebook.
This is a good suggestion because Facebook social media users are very much and if there is an assignment on MVP in this game to do it on Facebook, I think it will add interest in this game.
I also agree that this platform adds some of its tasks on social media Facebook because Facebook social media enjoys a lot of people when compared to VK and Twitter.
