This may sound like a crazy idea because it is, but would it be possible to implement "dual-wielding"? Like, when you pick up a tool, there is an option to use two of them at once. One would be where the cursor is while a mirror image of what you're holding appears on the other side and moves accordingly, allowing you to attack both feet at once.
On a completely different note, how is the next update coming along? Can't wait!
