It goes from 15 to 18, my guess is that it adds the normal hit to the critical.
This movie has it all: a cute witch girl, cool movement options, a cute witch girl, zips, a cute witch girl, boss quick kills, and a cute witch girl. Heck this game is OBVIOUSLY superior to Mega Man because it stars a cute witch girl. Apparently in the Japanese version of the game there were story cutscenes ala Ninja Gaiden so this game never got its best showing in the west. Despite starring a cute witch girl.
In fact I was thinking about the moving platforms AND that framerule. I've said that I don't know much about where the framerules are, so if there is no framerule applied between the underground section and the part with the hunchbacks, and if an improvement exists with the moving platforms, it could gain a framerule at that door.
And I've never bothered with framerules in the first TAS so I don't know them well, is the next one at the door after the hunchback-dropping birds?
Because taking all the time you need to test and finish the run is what matters, no need to rush ^^.
I have just tested this to see if it would sync on lsnes and with success it worked. I did try with the all bosses but it desyncs at the beginning of the conservatory unfortunately.
The "famous" horizontal zipping is actually constantly forward-ejecting onto 8-pixel grids plus slightly forward-sliding out of the grids every frame, which form a loop. If the Left or Right button on the D-pad is pressed in order to move Francesca out of the 8-pixel grids, the wall in front of her would only eject her backwards opposing her walking direction. That's why the horizontal zipping only works on Stage 2 AFAIK for it requires the D-pad-free sliding physics there.
For those thinking about TASing this, as DOS via libTAS is now closer to possibility, here's some info: Lemmings contains 120 levels, split into 4 segments. Oh no! More Lemmings contains 100 levels, split into 5 segments. Holiday Lemmings 1991 contains 4 levels, two of which are in ONML. A first TAS for this series might start here as it's short. Holiday Lemmings 1992 contains 4 levels, all unique. A first TAS for this series might start here as it's short. Holiday Lemmings 1993 contains 32 levels, split into 2 segments, all of which are also in 1994 version, so this game should be skipped if one wants to TAS a whole game instead of segment by segment. Holiday Lemmings 1994 contains 64 levels, split into 4 segments, including the 32 levels from the 1993 version.
So I guess no one submitted this?
