 Undefined Fantastic Object
The twelfth installment in the Touhou series. This game features a unique UFO system. Some enemies drop UFOs that come in three different colors: Red, Blue, and Green. By collecting 3 of the same color, or collecting one of each color, a giant UFO appears. The player must shoot it down in the time specified. There is a rumor that a flying treasure ship has been in Gensokyo since the beginning of spring. Reimu and Marisa, accompanied by Sanae Kochiya, decide to search for the ship.
As a vertical-scrolling shooter, the character always faces north. Enemies will appear on screen, and the player must shoot them down, while maneuvering through the patterns of bullets. Some stages have mid-bosses, bosses that appear in the middle of the stage. At the end of each stage, a boss appears. These bosses have multiple lives, backed up with many difficult Spell Cards.
- Arrow Keys - Move the character in the direction of the arrow pressed.
- Z - The 'Shot' button. Pressing Z shoots out bullets, and can be held down to continuously shoot.
- X - The 'Bomb' button. Pressing X uses one of the bombs.
- Shift (Left) - The 'Focus' button. Pressing Shift slows down the movement of the character, making it steadier to control.
- Esc - The pause button. Pressing it pauses the game, and brings you to a menu of options.
- ctrl (Left) - Fast forwards through dialogue.
Some of the enemies that appear on screen drop point icons. If the player gets enough points, they are rewarded with an extra life. Enemies also drop power-ups, which raises the character's power until it reaches 'Full Power Mode'. Upon reaching full power, all the bullets on screen are converted into points that are automatically collected. While at full power, if the character moves near the top of the screen, all of the items on screen are also automatically collected. It should be noted that a small amount of points are rewarded for shooting enemies, and a slightly higher amount of points are awarded for actually defeating them.
 Points Icons
The point icons dropped by enemies are just one of the ways of collecting points. The higher on the screen you are, the more points the icons are worth. The amount of points each icon is worth is shown upon collecting them. The value is shown in yellow text if you are able to collect them at their highest value, and in white text if their value is below maximum. Note that the maximum value gets higher as you play on harder modes.
There is a meter that keeps track of your power. It starts out at 0, when your attacks are the most weakest. By collecting Power-Ups, the number raises until it reaches 128, maximum power. When you reach this, a prompt will pop up that says 'Full Power Mode', and the power meter will show 'MAX' instead of a number.
