Play Castelian (Europe) on gb Online

Castelian came out for the Game Boy in 1991, developed by Bits Studios. It was one of those puzzle platformers that felt right at home on the handheld, offering a methodical challenge during an era when portable games were often simpler, quicker experiences. You don't hear much about it now, but it had a quiet presence.

You control a bouncing ball, navigating through a series of single-screen maze stages. The main goal is to reach the exit in each level, which involves pushing blocks to clear paths or create platforms while avoiding enemies that respawn if you leave the screen. The pacing is deliberate, almost puzzle-like, and the difficulty ramps up significantly with later stages demanding very precise movements and timing. It feels tense and satisfying when you finally thread a narrow gap or outmaneuver an enemy patrol after several attempts.
