Parachute

There's a little game
Called "parachute." It came
On my nano. Free!
It will be the death of me.

Actually, I've died many times in the game already. The idea is you're operating a rotating gun that shoots down attacking paratroopers and helicopters. You move the gun by circling your thumb or finger in that little wheel-like touchpad. But it's hard to control with precision.

It isn't really
That I'm a bad aim.
Surely the wheelie
Deserves all the blame!
