Lets get this right: Upperland Studios is just a name, Rockbot is developed by mostly a single person on free time, weekends and holidays.
We never got any money from the game, by contrary, we spend a lot buying devices and licences.
So, please, do not demand we finish Rockbot 2 soon, the game comes in second place after our personal lives and is just a hobby, not a profession.
Unless someone pays me to work only on Rockbot and leave my daily job, no release dates will be given
Meanwhile, you can get the beta and incomplete for the full version in out google plus community:
