How to Play

Your journey as the shrine’s defender begins the moment you start Crimson Fantasia. As Reimu Hakurei, your mission is to clear two intense stages packed with swarming youkai and intricate bullet patterns. Move Reimu using the arrow keys (or virtual joystick on mobile) and aim/shoot in any direction with the mouse or your device’s touch controls, embracing the classic twin-stick shooter experience.

Collect dropped items such as power-ups and score tokens by skillfully weaving through enemy fire. Swift movement is key—time your dodges and deliberate shots to maximize both survival and scoring. Each stage features waves of enemies and challenging bosses; watch for unique attack patterns and exploit brief moments where enemies let their guard down for higher point gains.

Beginner tips: Focus on mastering the basics—fluid movement and steady shooting. Always watch the entire screen to anticipate bullet trajectories and enemy spawns. Don’t forget to manage your items; picking them up at just the right moment can spike your score. Aim to chain combos and finish levels quickly for leaderboard bonuses. And remember, a confident balance of offense and evasion will reward you!

Jump in for quick sessions or hone your skills for global domination. With intuitive controls and a forgiving learning curve, Crimson Fantasia welcomes all players while offering plenty for bullet hell enthusiasts to master.
