In order to save their school after it turns into a massive demonic castle, two "Demon Hunter" sisters slash and shoot their way through this 2D action adventure. Players can swap between control of both characters on the fly, each with entirely different skillsets.
Players can seamlessly swap between the two playable characters, Shinobu and Maya, at any time during gameplay. Shinobu excels at ranged combat with her guns, boasting higher health to take hits. In contrast, Maya is a close-range brawler with lower health but devastating melee attacks. Switching between these complementary playstyles is crucial to adapting to different enemy types and obstacles.
The fairly linear levels feature multiple paths and hidden secrets to uncover. As players acquire new subweapons and abilities, they can backtrack to access previously inaccessible areas. Subweapons serve not just as offensive options, but also as traversal tools, such as a grappling hook or umbrella glider. Managing the limited weapon points used to activate subweapons becomes an important strategic element.
Each stage presents its own unique environmental hazards and enemy types, requiring players to leverage the strengths of both Shinobu and Maya. Hidden rooms and alternate paths are often only accessible with specific subweapons, encouraging thorough exploration. The boss battles stand out as particularly memorable challenges. Defeating each boss yields new subweapons, further expanding the player's arsenal and options for tackling future encounters.
The game offers multiple difficulty settings, from the more casual "Casual" mode to the punishing "Legend" difficulty. Players can freely adjust the challenge level at any time to suit their skill and preferences. Additionally, the game features multiple endings and reasons to revisit levels, such as finding all the missing students or collecting hidden items. This, combined with the ability to swap between characters and experiment with subweapons, provides a solid amount of replayability for those seeking to fully complete the experience.
