Skycrane Copter has been released, and you can download it from Google Play: Play.google.com
It's fairly challenging because the helicopters movements are based on physics, and you have to lift heavy objects with the magnet that's attached to the copter! Try it out.
Currently the game has ten levels, but I'll be looking into making more content in future, if people want that.
Thanks for reading, and leave feedback on what you think about the game, if you want to.
