The player controls two characters instead of just one, each with different abilities. Head can jump higher than Heels, control himself in the air, and fire doughnuts from a hooter to paralyze enemies; while Heels can run twice as fast as Head, climb certain staircases that Head cannot, and carry objects around a room in a bag. These abilities become complementary when the player combines them together after completing roughly a sixth of the game. Compared to its predecessors, the game offers unique and revolutionary gameplay, complex puzzles, and more than 300 rooms to explore. Drummond contributed some famously surreal touches, including robots that bore a remarkable resemblance to the head of Prince Charles on the body of a Dalek. Other surreal touches include enemies with the heads of elephants and staircases made of dogs that teleport themselves away as soon as Head enters the room.
Plot
Headus Mouthion and Footus Underium are two spies from the planet Freedom. They are sent to Blacktooth to liberate the enslaved planets of Penitentiary, Safari, Book World and Egyptus, and then to defeat the Emperor to prevent further planets falling under his rule. Captured and separated, the spies are placed in the prison headquarters of Castle Blacktooth and must first escape, then break throughthe market to the orbiting Moonbase where they can teleport down to the planets to locate and reobtain the stolen crowns. Liberation of the planets and defeat of the Emperor will allow Head and Heels to return to Freedom as heroes.
Development
re-used and modified the isometric engine he created for Batman to support the control of 2 players instead of just 1. Modifications were made to the code for the C64 version to lower processor load, but in the end there was very little difference between the versions.
Critical reaction
Your Sinclair awarded Head over Heels 9/10 in the June 1987 issue and the game was placed at number 5 in the Your Sinclair official top 100. Sinclair User also awarded 9/10.
Crashmagazine gave Head over Heels 97% and called the game "The best fun you're likely to have with a Spectrum for quite some time".
Zzap!64 gave the Commodore 64 conversion of the game 98%: enough for its coveted Gold Medal Award; the joint highest score in the magazine's history; and the first Gold Medal of the year - in its August 1987 issue. It was described as "An all time classic - not to be missed for any reason".
