You've got the start of an interesting game here.
I like the concept of being able to swap out which weapons you want to hold onto, it brought to mind Castlevania sub-weapon swapping. It's an intriguing concept for a game of this style and could be interesting to see what could be done from a gameplay perspective if the idea is expanded upon.
Most of the abilities were pretty standard but worked just fine. The dash ability was pretty fun to play around with, launched the character every which way. The grab wall climbing was pretty good as well. And it was fun breaking out of bounds with them XD
