About this game
Description
Supplied by the Steam store
This is a fan-made game based on the Touhou Project. At its core, it is a simple vertical-scrolling 2D shooter where you move and shoot. It features 26 playable characters, two game modes, dynamic difficulty, randomized patterns, and a chaotic, eclectic atmosphere.
<< Defeat enemies to level up! >>
Defeating enemies increases your SP; reaching a certain threshold causes you to level up. This powers up your shots and restores HP, but also increases the difficulty.
<< Collect "Gain" to prepare for hits! >>
You gain points by defeating enemies, shooting bosses, shooting Udon boxes, or refraining from firing your weapon.
Having 5 or more Gain activates an auto-bomb upon taking a hit; 15 or more reduces damage taken; and 30 or more enables automatic HP recovery.
<< UdonGain Mode >>
Features three arcade-style routes and random stages. Rescuing Daiyousei, Koakuma, or Mystia allows them to fight alongside you. Shooting Udon Boxes replenishes your Gain. You can view illustrations of the characters you've cleared the game with in the gallery.
<< Alternative Mode >>
Nine routes tuned specifically for score attacks, offering a more stripped-down experience. Rescue boxes and Udon Boxes do not appear; instead, "Rank Bonus Boxes" appear.
<< Playable Character >>
