WOW, amazing work. I can't imagine how much time and effort it takes to make these, but these are deff one of the best packages for Side scrolling Animations.
Honestly above and beyond as most other packages usually only have like 7-8 animation types. But your work is just top notch and a must have for anyone interested in any kinda side view action game as these are so valuable for different types of animations when prototyping.
