Probably need to use the gloves from W1 on this boss, I can double hit him consistently, should save about 140f. Unless there's a way to get up to the lift by ground pounding the boss, but it doesn't seem like it.
Clipping in 6-4 is about 70f faster. Couldn't inhale both enemies from the top of the platform, it was close though, maybe I can get that working.
7077f faster totally.
Very much fun going back to world 5 to kill an addionl enemy to cycle the RNG for an ~10f improvement in the first room of 6-1.
6841 frames faster totally.
Another level down to one health bar. Abused lag and position error tolerance to do R/D pushdowns and multiple throws in one jump to get it down to it.
48 frames faster than v3 and totally 298 frames than published movie.
383 frames saved in this level, total 1248.
Main improvement comes from pushing down bonus counter 4 times faster while riding the mine cart by doing R|L/D pushdowns(old was 15; new is 1 bonus bar). Also more entertaining glitchy-ness with the mine cart.
