[original] Touhou Kōryūdō ~ Unconnected Marketeers
Touhou Project Vol. 18.
Avoid the colorful barrage of fireworks and destroy your enemies.
Use your technique and memory to challenge the short-lived battle!
Each of the previous Touhou games has had a different core system, but Niji Ryuudo allows you to strengthen your own machine.
The difficulty level is a bit higher than in other Touhou Project shooters, and beginners will have quite a hard time.
