About Touhou Seirensen ~ Undefined Fantastic Object.

✦ AI summary

Touhou Seirensen ~ Undefined Fantastic Object is a bullet-hell shoot-em-up where you pilot a character through waves of enemies and projectiles while collecting colorful Ventura items that spawn UFOs with unique item-absorption mechanics. The game's standout feature is its UFO system where matching three Ventura items of the same color summons differently-colored UFOs that vacuum up items and bullets, creating strategic risk-reward moments where you hunt down UFOs to recover stolen power-ups and points before they escape.
