Touhou Fuujinroku: Mountain of Faith is an action-packed game designed for Windows, featuring two distinct playable characters, each equipped with three unique weapon types. Unlike traditional systems, players do not have personalized spell card bombs; however, they can enhance their gameplay by collecting power items that generate up to four option satellites. These satellites adapt to the selected character and weapon, providing strategic depth as they aid in firing bullets and offer tactical choices in focus-fire mode.

The game introduces an innovative scoring system centered around the Faith meter, which players must manage effectively. The gauge can be replenished by defeating enemies and collecting point items, which also contribute to increasing the Faith value. This value, starting from a minimum of 50,000, directly influences the point values of collected items and spell card bonuses. Players must navigate the challenges while optimizing their Faith gauge to maximize their score, creating a compelling gameplay experience.
