Cirno's remaining lives are represented in a percentage form. When you lose a life, you'll lose 100% Motivation. If this would be enough to bring you under 0%, you'll get a game over.
Motivation will increase steadily as you destroy enemies and use Ice Power. Using Ice Power to destroy enemies will increase it more quickly.
Shot power is represented by a percentage. By using Ice Power and Perfect Freeze you can increase this power. For example, if you freeze 30% of the screen, it will add 30% to the shot power. There are 16 levels of shots. The percentage values are the same across all difficulties except for Easy. There isn't an easy formula to convert between power level and frozen area, but it generally starts off fast (50% will get you to the next level) and slows down (it takes 400% to get from Lvl 15 to Max).
Below is a conversion table for convenience.
Cirno has an Ice Power meter that works much like the camera in Shoot the Bullet and Double Spoiler. It will charge slowly from 0% to 100%. In order to charge it manually, you can hold down Z. By holding down Z and then releasing it, Cirno will release the Ice Power that was stored. If your charge is under 30%, you can't use it. You will hear a "click" sound when it is possible.
When Cirno releases her Ice Power, it will freeze all nearby bullets. It will then freeze all bullets close to those bullets, and so on, for a certain period of time. After the period of time ends, the bullets will all disappear, and any enemies that get hit by the "shattering" ice will be damaged quite a bit.
Depending on what percentage of Cirno's capacity you charged, the resulting effect will last longer. If you didn't charge up to over 30%, nothing will happen and you will resume firing normally: the accumulated power won't be wasted either.
After the effect ends, you will receive a point bonus based on how much of the screen you filled up with ice (see table below). If you froze under 30% of the screen, your Ice Power will reset to 10% and your Perfect Freeze meter will increase with:
1/4*(Percentage of screen frozen) + 2.5%
If you froze over 30% of the screen, your Ice Power will reset to 20% and your Perfect Freeze meter will increase by 20%.
Shooting will slow down the automatic generation if your shots aren't hitting anything. Hitting something will increase the rate of regeneration, and grazing will add even more to it.
|Percentage of Screen Frozen||Point Bonus|
(Linearly interpolate for intermediate values, with percentages in increments of 0.01%.)
Cirno's bomb freezes all non-laser bullets on the screen (note that unlike her Ice Power, it will also freeze fireballs). Unlike bombs in other games, your Perfect Freeze meter will start at 0%, so you don't have any bombs available at the start.
The bomb takes a while to fully activate, although the animation starts immediately. Cirno is invincible during the duration of the animation, but the bullets and fireballs won't freeze for a few seconds. This is incredibly useful for getting through a difficult section, but it can throw off your timing if you are trying to freeze a specific bullet pattern for score/power/motivation.
Once the bomb goes off and freezes everything on the screen, the ice will behave normally: normal bullets (non-fire, non-laser) will freeze, enemies will get damaged based on how much ice breaks near them once it shatters, and you will receive a point bonus (identical to that of Ice Power) based on how much of the screen was frozen. The only difference is that the freeze will not charge up your Perfect Freeze meter.
Each time you use the bomb, the Perfect Freeze meter will decrease by 100%. If it's 99% or below, you cannot use it. The meter itself can increase all the way to 300%, contrary to what it says in the manual.
When you die, you'll gain 25% to Perfect Freeze, but not going over 300%).
Cirno can run into most grunt enemies without getting hit, unlike other Touhou games. However, midbosses and bosses will still cause Cirno to lose a life.
When enemies are destroyed they drop point items; as the name suggests they serve as a source of points. Regular items that have been auto-collected are worth 1000 points, while items that are collected manually are worth between 240 and 720 points. Destroying enemies using ice causes them to drop special point items that are larger and lighter in colour than regular items; these are worth four times as much as regular point items.
This game has a medal system for spellcards.
- A Narrow Victory! - Card beaten, but you failed the bonus, because you died, used a bomb, or ran out of time. (For Marisa's last two cards, running out of time will not fail the bonus.)
- A No-Miss Victory! - Card beaten without dying or bombing, but you froze bullets.
- A No-Ice Victory! - Card beaten without dying, bombing, or freezing any bullets.
If you earn a silver or gold medal on a spell card, you'll receive a point bonus.
This bonus starts at out at a value equal to:
100,000 * (stage number + difficulty value)
with difficulty value being:
Bonuses in Extra have a starting value of 500,000.
With the exception of Marisa's last two cards, this bonus decreases over time, starting 5 seconds after the spell card starts. In Extra, it decreases more quickly if you happen to be in one of Marisa's non-lethal lasers. It will not decrease below 10.
To unlock the extra stage, you must reach all 6 endings without continuing on any difficulty mode.
Please note that a number of "bugs" are simply the result of not playing the game in Japanese locale. Please use something like Microsoft AppLocale, or outright change your system locale when playing Japanese games, because it will save a lot of headache and the fonts will stop being gibberish.
- The bomb counter can display an incorrect number. Affects: unspecified <toggledisplay showtext="Show details" hidetext="Hide details">
When performing a deathbomb, the bomb counter on the bottom left of the screen isn't affected, thus displaying an incorrect number of bomb.</toggledisplay>
- "Revenge bullets" will still shoot during dialogue. Affects: unspecified <toggledisplay showtext="Show details" hidetext="Hide details">
When enemies are cleared when dialogue begins on Hard or Lunatic, the "revenge bullets" still shoot even though all bullets are supposed to be cleared. However, you're invincible during dialogue, so it can't actually kill you.</toggledisplay>
- You can cause the game to continue indefinitely in the last spell of stage 3. Affects: unspecified <toggledisplay showtext="Show details" hidetext="Hide details">
When facing the fairies' last spell in stage 3, you can cause the game to continue indefinitely by defeating one or two of the "side character" fairies (the two who aren't the main boss) while defeating the boss fairy at the same time (usually via freezing). The spell will end and the fairies (however many are left) will scatter, but the stage will never end. You can still shoot and collide with the lingering fairies before they drift out of range.</toggledisplay>
- "Give Up and Retry" may cause the game to crash. Affects: unspecified <toggledisplay showtext="Show details" hidetext="Hide details">
Selecting "Give Up and Retry" after dying may crash the game (on XP, the "encountered a problem and needs to close" dialog is displayed; however, there seems to be no problem if the game is played on Vista). This was observed after running out of continues on B1-3 during the midboss battle with Luna, but specific conditions are unknown.</toggledisplay>
- "Give Up and Retry" on various stages will cause the recorded route of all subsequent runs to be incorrect. Affects: unspecified <toggledisplay showtext="Show details" hidetext="Hide details">
Selecting "Give Up and Retry" on stages A2-2, A2-3, B2-2, B2-3, C2-2, or C2-3 will cause the recorded route of all subsequent runs to be shifted down one route in the sequence A1 → A2 → B1 → B2 → C1 → C2, until you return to the menu. Repeating the glitch results in additional shifts; for example, doing the glitch twice then playing A2 will result in the recorded route becoming B2. Shifting past C2 appears to cause crashes, but the crash may not occur immediately. This causes the score to be recorded to the wrong scoreboard (e.g. a score from A1 might be recorded on the B1 scoreboard). If you clear the game, the wrong ending will also occur, and for the purposes of unlocking Extra, the wrong path will be marked as cleared. However, the score entry and replay will still record the correct path.</toggledisplay>
- Replays of spell card clears will award you a bronze medal. Affects: unspecified <toggledisplay showtext="Show details" hidetext="Hide details">
If you watch a replay that clears a particular spellcard, the game will award you with a bronze medal for that card, even if you haven't cleared it yourself.</toggledisplay>
- A replay of stage C2-X will incorrectly display as C1-X. Affects: unspecified <toggledisplay showtext="Show details" hidetext="Hide details">
When selecting a replay to view and selecting a replay of stage C2-X, it will incorrectly display as C1-X in the stage selection.</toggledisplay>
- On the pause menu, "Replay Again" will open the in-game manual. Affects: unspecified <toggledisplay showtext="Show details" hidetext="Hide details">
On the pause menu of a replay, the third option of "Replay Again" opens the in-game manual, while selecting the hidden option one step lower will replay the replay.</toggledisplay>
- Misnamed replays may crash. Affects: unspecified <toggledisplay showtext="Show details" hidetext="Hide details">
There is an issue with the Replay menu where it crashes when you have a misnamed replay (for example, you saved a replay for Route A1 and the replay registered as B1). To fix this, save another replay.</toggledisplay>
- Saving replays may crash after defeating a first stage boss. Affects: unspecified <toggledisplay showtext="Show details" hidetext="Hide details">
If you save a replay while in route selection after defeating a first stage boss, the replay can make the game crash.</toggledisplay>
