Thank you for your thoughts but an app like that wouldn't work well in terms of benefits/costs.
It would most likely attract only players who already play BD and no new ones.
Doing an app nowadays means to spend a crazy amount of money to add good graphics, an entertaining gameplay, an appealing UI, marketing strategies, QA testing, ... oh god, I think I could add 100 more points.
And its only worth the effort when you think big. Reaching out to have 1 million active players daily.
This can honestly not being achieved with BD as it is now.
So investors needs to be found and contracts negotiated and lawyers hired.
Its a BIG task.
I guess ^_^ still I can dream a little :')
