Play Alex Kidd - The Lost Stars (World) Online

Alex Kidd: The Lost Stars came out for the Sega Master System in 1986, developed and published by Sega. It was one of the earlier platformers on the system, arriving before Sonic made speed the focus; instead, it offered a methodical, screen by screen challenge that felt typical of mid 80s action games.

You control Alex Kidd, running and jumping through themed stages to collect the twelve zodiac signs stolen by an evil force. The game progresses one screen at a time; you clear enemies and obstacles, then move to the next area when the screen is clear. Signature mechanics include throwing punches to defeat foes and navigating precise jumps over gaps or onto moving platforms. The pacing is deliberate, and the difficulty can be steep, especially with limited lives and instant death pits. It feels like a careful, sometimes tense test of timing and memory.
