2 frames saved in Stage 16 thanks to door frame rule... I guess?
All I've done was delaying the stair descending by 1 frame, then the boss skip resulted 2 frames faster.
Refined test based on the first draft by FatRatKnight... Though it got 14 frames slower than the current main WIP. There is small room for improvement btw...
Edit: After some quick tests, I've noted that the first hit to the miniboss 6 would be dealt 6 frames later in the best case possible, making it unable to save any frame.
