Really like the idea! But why would I provide service to an alien while they only give me 2 ◊ lol
One advice would be adding the speed up button. I only want those alien to wait not myself.
No aliens give that little, the amount of money displayed is how much cash the alien has left. That means you did a good job since you made them spend all their money! Speed up button is definitely a missed opportunity.
Ahh, I thought that number represents how much they will give me. Didn't notice that number is changing.
