Astyanax
Astyanax is a side-scrolling action platformer released by Jaleco in 1990. Players control a warrior equipped with a magical sword and battle through fantasy-themed levels filled with enemies and obstacles. The combat system centers on sword attacks, and the game features various power-ups that enhance the protagonist's abilities, including sword improvements and temporary invincibility. The gameplay follows a traditional platformer structure with multiple stages, each ending in boss encounters. Players navigate through different environments while defeating enemies and collecting items. The game employs a lives system where running out of health results in losing a life, and collecting enough power-ups restores health. Controls are straightforward: directional input to move, a button for jumping, and another for attacking with the sword. Astyanax offers moderate difficulty with engaging combat mechanics that differentiate it from purely platforming-focused action games of its era.
