This game is really beautiful to me because 1. The bubble gum girl is really cute I like her design 2. My first attemp to make a video was a platformer with the mechanic of using the knockback of a shotgun and other weapons not only as a way to deal damage but as a double jump and you my friend are making my failed attempt a reality and I really respect that. I wish to see you work on this further because this mechanic is REALLY fun and can be expanded and on top of that you implemented innertia so you can go at break neck speed with some good level design. One feedback I will point out is that the crounching sound is too high pitched and can be annoying but as I said, maybe is pure bias in my part but you got something fun with this concept, please explore it.
