I was wondering, how many patterns in the Touhou series have timeout phases? I've made a list of the ones I know of (including most Extra final spells). Are there any others?
I'll define a timeout phase as a sudden jump in difficulty if you take longer than a pattern intends you to take, usually intended to prevent trivializing a pattern that starts out easy but becomes more difficult with damage. It may or may not be more difficult than the pattern normally becomes.
(Note that it needs to be sudden, and from taking more time than intended. If it becomes gradually more difficult over time, or it's something like VoWG or a survival spell where it's expected to reach the final phase, it doesn't qualify.)
