i've tried it on mobile too, and you're right, it's better. i got 73 this time. i'm using an strategy that feels like cheating, i just go from level 10 to 1 stopping on each level when i forget where a passenger wants to go, but when it gets too crowded it doesn't work as well ;) i think the elevator should decelerate faster, and the passengers could maybe remind you after a certain time which level they'd like to go
by the way, i'm sorry it has to be this way but my team and i are a bit short on ratings, would you mind giving a look at our game? https://itch.io/jam/gmtk-2019/rate/462969
