the art is nice, the music is good, and the idea is amazing
buy it is kind of annoying and boring when you're in floor 4 and get a package that is supposed to be delivered in floor 200
you can make it so there's 100 floors only, and you can add a visible timer for every package and if any of the timers reach 0 you lose
you can make it so that you have to go to a certain floor that will give you a package then you'll have to deliver that package to another floor, I'm just giving you ideas, in case you wanted to make your game better.
