Saved 1 frame on 3-1 with new route:
- subpos manipulation on previous non-boss level
- interrupt juggling to maximize X pos
- interrupt juggling for 1 frame between dog and knife tosser sacrificing only half pixel
- using "fastest" knife-cheetah (probably a half pixel can be saved?) positions (interrupt juggling timed/positioned to spawn them as fast as possible)
Sweet. Only one problem. 3-2 knife tosser became angry and hurls knives.
