Developed by a team formed by only two people, Planet Apolion is based on the mechanics of the classic shoot ’em up genre, combined with elements of adventure and RPG gameplay. The game can be enjoyed through two different game modes; an Arcade mode in which the protagonist undergoes a series of purely action levels, defeating enemies and accumulating points through different stages and routes which can be selected from a map, and an Adventure-RPG mode, where you face enemies and other challenges, including puzzle-solving to discover new areas, choosing different routes within a map of an open world, obtaining different achievements, weapons and equipment to prepare the protagonist for defeating enemies with different characteristics, a shop system, and customization to use such equipment. Also, the player will be able to explore the 8 zones divided into 16 stages, alternating between side-scroll and vertical-scroll and changing direction at any time
