I enjoy super difficult games (Meatboy Track Pack for instance), but I can also love a game that requires little thinking. Instead of just playing the game, I tried to make different ships. I made a ship with three magnets and Electricity only (which didn't work), and later on three magnets and only rockets (which worked perfectly). I prefered the second to last upgrade, but maybe that's just me. Great game!
