Chahi used an Amiga 500 to create the final game, using Devpac Assembler to program the game engine and polygon outlines and GFA BASIC to create the game's editor. Using a genlock, he imported recordings of his little brother from a video camera to use for rotoscoping animations. He used a tape recorder to record the sound effects for the game. He drew the background art with Deluxe Paint.[2] The game is the first 2D game to use polygons for all of its graphics, as opposed to the more common sprites, which created a distinctive visual style. It took advantage of the computer hardware at that time to display full-screen animation (Amiga 500 and Atari ST were 68000 based, PC AT machines would have been 80286).
