I'm really surprised how much I liked this game.
It was fun, super easy to get rich and purchase all items, and the achievements aren't too hard either.
For the 3,000,000 jump I would just wait for his peak to be around 80 feet, then I'd shoot him with the golden gun, that would send him flying +1,200 ft.
My reason for letting him peak at 80ft is because thats where I tend to find the most ammo + cash items, and that makes it incredibly easy to get the 3,000,000 launch.
Hope that helps.
