 * Perf.png Perfect: ± 3 frames (50 ms)
 * Hit3.png Great: ± 6 frames (100 ms)
 * Hit2.png Good: ± 7 frames (116.67 ms)
 * Hit1.png Bad: ± 8 frames (133.33 ms)

Gameplay Notes

 * Starting health is 1000. Hit1.png Bad deals -50 health, and misses deal -100 health. Hit2.png Goods do not reduce health but break combo.
 * Ticks in the middle of slider holds are guaranteed to be perfect when hit.
 * This makes "All Great" and "All Good" plays impossible on charts that have slider ticks.
 * Holds only detect the position and hold state on ticks and the release note.
 * As long as a finger is still on contact with the screen for a hold, moving that finger will not drop the hold. Ticks will "check" the position and drop the hold if the finger is not there, however.
