Challenge: Speed Devil

In this challenge, you have a unique control over how quickly bloons spawn. But, there is a time limit. If you don't finish off all bloons in the round's time limit, you're out.

Mechanics
Let one bloon through by pressing the I key. Let a tight cluster through by holding I for longer. You start with $10000. If there is more than 1 type of bloon in that round, they will be released in the order that they are listed below. Good luck.
