Shatterdome has updated his game”PSP Helicopter”. Release notes:

I added some point balls that you can now collect, they are worth 150 and the multiplier affects them…also you won’t run out of buildings, but they never speed up, so i’ll figure that out yet, I have some ideas…Also the point balls require new graphics and there is a death animation now, so you’ll have to replace the old folder if you’ve checked this out before…
