For people not getting their BotD, Chrome is probably blocking Flash (there will be a little jigsaw piece with a red cross icon in the address bar). Click on the icon and allow Flash, and the badges will work.
Props to Ragnar@Kong support for telling me that.
The frog on the log section is bloody annoying mainly due to the terrible collision detection. Either shorten it, or improve the detection, especially when the fish is coming in at a low angle.
Big explosions are cool, but the game is far too frustrating being as it is totally reliant on the more ships booster. All other boosters are worst than pointless once you've (quickly) ground your way up to buying all upgrades. In fact, the other booster are liabilities as they take up slots.
Needs indication for how difficult a port is to attack; getting very tiresome getting nuked by ports with three ships firing three time with first initiative...
Bug with paint mixing rooms.
If you move to a different room after he's stood on one of the stones, that stone will stay activated. If you then stand on the other stone, you won't be able to get back onto the first stone.
As mentioned by other people, the key to the elevators is to limit your stacks.
I limited mine to each shaft serving just 5 floors and only ever get the very rare complaint; the customers don't mind waiting a bit of time for lots of elevators, but hate waiting a lot of time for one elevator ;)
The only downside to this plan is that it costs a lot more for the individual elevator shafts.
To maximise your earnings, and build up a fund for when you unlock your next star, build one room less than your next star limit and wait. Also build as much of the elevator infrastructure as you can before the next star unlocks so that when it happens, you can spend all your funds on the new room types that the customers will be demanding.
One thing, don't both building more than one outdoor restaurant; they never make any profit.
Top tip is to stock up on plenty of money before unlocking the next star; once new rooms are available, the customers will get very demanding for them!
