A more efficient elevator system! (But extremely expensive)
Having alternating elevator paths seems to make everyone happy even with every space filled with rooms up to max height~ As in, having 5 rows of elevators, then a space, then another 5 rows upwards, and so on, with another elevator next to it taking up the open spaces of the first with its own 5 rows (6 rows for the first one on the ground floor).
For the elevators, I was able to have everyone happy with four elevators to max height.
At floor 25, end the first ten person elevator, and right next to it start another elevator that goes to the top. Repeat this on the other side of your tower~
Everyone is nice and happy then!
I made it to level 63 before finally deciding the game had nice concept, but the physics and controls are absolutely pathetic and should not have been released. Ever.
