- 4-3 second screen: 6 frames saved by boosting off knife and not taking damage later but wait.
- 4-3 third screen: 2 frames lost because bullet guy's 1st bullet would go left if I don't freeze enough (timer...)
Also 3 frames lost because of frame rule (150:16 the timer at boss is different thing I guess)
And improved 2 frames on 5-1. Which will desync. Time to reimplement successful positionings.
