Spaceblip HD 1.0

the author of this app says:

A new twist on the classic gameplay, go beyond playing in just four directions. Enter the dangerous deep space with your brand new hyperdrive equipped mining ship and start collecting asteroids. Use intuitive touch controls or d-pad to steer the ship clear of your engine's trail, which will keep getting longer and longer. But beware, you are not alone out there: as you progress, enemy ships will appear and will leave trails of their own.
