that spelt out the word "HEROS", playing all 51 normal levels (6 of the secret levels are only accessible via a special password, and are not counted towards the normal level total), or playing through the 6 previously mentioned special secret levels. The password to obtain these levels had to be obtained by evaluating three math expressions that appeared during the credits, where they are called "a silly maths equation". In the "HEROS" ending, the player is congratulated for finding the ending, and then asked, "...but are you good at maths?". Development The Puggsy character originally appeared in an Amiga demo in 1990 named Puggs in Space, which was created and designed by Dionysus—a demogroup formed by Lee Carus, Alan McCarthy and Tim Wright. The management of Psygnosis was impressed by the demo, and asked Dionysus to develop a game based around Puggsy. However, the contract with Psygnosis to produce a game was short-lived; Wright said the company "didn't really 'get' where we were going with the game". The demogroup was pulled out of the game's development, which was then shifted to Traveller's Tales. Psygnosis asked Traveller's Tales if they could develop a game using the character from the demo. Puggsy was designed and programmed by Jon Burton, while Andy Ingram handled the graphic design and artwork for the game. While the character design for Puggsy was retained from the demo, the developers changed his colour from red to orange to prevent the consoles from colour bleeding. Wright recalled that Dionysus's version was going to be similar to LittleBigPlanet, while Traveller's Tales' version was created as a standard platformer. The object physics in Puggsy was inspired by Super Mario World, a game Burton had enjoyed. Burton decided to create a Super Mario World-type game, but with puzzles being based on physical objects with different properties such as buoyancy, weight, friction and so on. As Puggsy was deemed too complicated for novice players, the training levels were added late in development in response to the publisher's input. Burton noted that the training levels would give the impression of a basic platformer. The music was written by Matt Furniss, an employee of Krisalis Software. Wright created cover versions of Furniss' tunes for the Amiga version and added a Puggsy demo theme into a tail end of one of the pieces. Wright found Furniss' music "really well written and fun to convert to
