Expedited Shipping

Use w,a,s,d to control movement, space drops crates behind the truck.
Every 10 crates delivered a 2000 act time crate spawns, and 2 money crates spawn ($25, $100, $500 -> 50%, 30%, 20% of the time).
See how much money you can get before the time hits 0!

Please suggest things in the comments! Thanks!
