hey:) you can use the WSAD or the arrows key to move and use left mouse button to destroy crates if that's what you mean?
I meant of how it moves you know, I think the jump its a little bit floaty, but its not a big deal I think I'm the only one that felt like that
If you don't undersantd there is a video of GMTK (sorry Brackeys) talking about the movement of Madelyn in Celeste, I know it a totally differrent game but I think it could give you some ideas.
