Really well done! Movement feels really good, and I like the mix of the gravity switching with more of a metroidvania with the combat. I would perhaps adjust the movement to be a little quicker, but thats just something you have to play with.
The one thing that frustrated me, is that gravity does not seem to switch all the time when I right click. I am not sure if that is a bug, or if there is an intentional cooldown. If there is, it really needs to be communicated somehow.
