By the way… I know it’s not the best time to say things like this, and also I know that there are many other improveable places, but… Well… At frame ~24797 in your last gmv, it is possible to save some frames by performing spindash through object instead of breaking that thing normally. Also, your Y subpixel value at that point is only 1, if you maximize it (make close to 255), the improvement will grow even more. I managed to save 17 frames in a quite dirty attempt, it is still improveable, as I lost some frames for alignment, which could be done better.
Think of the subpixels as of your position inside the current pixel, you can be slightly higher or lower, it is useful sometimes. In this particular case (when doing spindash through object there), having lower Y subpixel value makes you stay a bit higher and thus fall into the tube (until you interact with it) a few (up to 2-3) frames longer.
This is just a demo.
