Mobile Game of the Week: Unmechanical (iOS)

This PC puzzler from 2012 has just arrived on iOS devices, and its nice graphics and smart puzzle design make the transition without any problems. The new control scheme almost bungles the whole operation, though, and makes me think Unmechanical is best left to the computer.
In Unmechanical I pilot a tiny robot that looks like a decaying apple as it flies like a helicopter through a series of mysterious, puzzle-filled mazes. The control scheme is similar to the classic point and click but with persistent motion and updated for touch-screens. I touch a spot and my little buddy floats continually in that direction until I lift my finger or until he runs into a wall. He’s slow to start, slow to stop and slow to change direction, though, making it hard to guide him as precisely as I’d like. It’s a poor substitute for a joypad or the WASD keys.
