It works fine. The grays have been bullied.
As for controls my impressions were that I would like to have an option to cancel throwing and quickly tapping movement keys should move the character more (I should be able to adjust my position in slightly bigger steps). It's also so much more comfortable to use IJKL + arrows.
The rest of the grab/throw feels alright. If you want responsiveness over commitment you could allow to change direction of the grab right after it already started.
