Touhou Kinjoukyou ～ Fossilized Wonders. is the twentieth Touhou Project entry, presented as a vertical-scrolling bullet-hell shooter. Its story begins with disturbances in Gensokyo that few people have noticed. Reimu Hakurei heads toward a sacred sanctuary at the foot of the mountain, confronting the anomalies that point to something amiss.
Choose between Reimu and Marisa, then select a difficulty and configure mutation stones. The game features eight Anomaly Stones, with equipment slots for main, diffusion, concentration, and support stones. Initially, only the main stone can be changed; playing unlocks stones for the other slots. Because each stone has a different effect, experimenting with combinations is part of preparing for the shooting stages.
The design emphasizes a classic form of Touhou bullet-hell action, built around character choice and customizable equipment rather than a departure from the series’ shooting roots. Reimu is a human priestess whose ability is mainly flying, while Marisa is a human wizard who uses magic. For detailed system explanations, the game points players to its manual, available from the title screen or the pause screen during play.
