stick & a friend who is still playing the game suggested I go back to it & try again.
So what's changed since July last year.
You can now customise your floor names, missions to complete to gain extra bux's, share your tower on the internet (http://towers.nimblebit.com/) - currently unavailable & stars next to floors show you if you have any bitizens in their dream job.
Upgrade floors - you can upgrade a floor to increase the amount of stock held but this cost bux's, I'm not sure how much of percentage stock upgrade this increases?
What is surprising when I reinstalled the game was that it had my old save file from last July so I carried on building from floor 35. Currently on floor 39 - will show my tower when the sharetower feature is back on-line.
So who else is still playing this digital crack. One more smoke?
