Improved 5-1 with a few frames by different route (bird boost, ducking mostly)
- 2-2 3rd screen: a half pixel save is not enough to improve it.
- 3-2: no matter how you sacrifice position, birdy won't be good for 2 times like in these WIPs
- 4-2: probably unimprovable
I don't know if the 4-3 2nd screen bullet guy can be remanipulated to shoot the first bullet properly, it should save a few frames because of the timer limit. I tried changing subposes and interrupt juggling, didn't had real impact on him (he is timer based too).
