CLARC. From the app description:
> This grid-based genre mix combines complex spatial puzzles with arcade style action elements and an epic storyline. As the story unfolds, the nerdy forklift robot Clarc will encounter partying robots, attractive nuclear missiles and intoxicated supercomputers. He sets out to repair his production facility on Mars and fights to rescue his friends from the intruding spaceship, M.O.T.H.E.R.
Lite version so you can try before you buy, then full paid version.
