Promises turned out to be empty:
1. released game is not functioning on mobile devices (I am not gonna even comment on how 'awesome' this game is)
2. this game has nothing in common with crypto and blockchain, it is just another mobile game that doesn't work and is at best dumb
3. devs have announced IPO out of blue, essentially selling their premine through IPO

Despite all of this, devs are doing quite well in terms of collection. As of now they have collected 170 BTC from Chinese investors (you can look by the e-mail addresses that every investor has Chinese e-mail address). IPO is being hosted by an unknown Chinese exchange https://www.51btc.com/crowd/project. Moreover, after this shitty game release someone has just invested 40 BTC into this 'company'.
