Alex Kidd in Miracle World is a 2D platform game. The player must finish levels and overcome obstacles and puzzles in both scrolling and single-screen environments. Throughout the 17 stages, Alex faces many monsters and the three henchmen of Janken the Great, before facing Janken himself.
Alex's punching ability is used to destroy enemies and to break rocks in order to access new paths and to collect items such as money which can then be used to purchase other items including vehicles such as motorbikes and helicopters. At the end of many stages, Alex plays jan-ken-pon (rock-paper-scissors) with one of Janken's henchmen. Alex dies with one hit, or by losing a game of rock, paper, scissors.
The game has no save system, but by holding the directional pad up and pressing the 2 button eight times at the Game Over screen, the player will restart the level with three new lives, at a cost of 400 Baums (the in-game currency).
