Place blocks with the mouse. Press Z and C to switch between block types. Press space to exit block-placing mode (you can still move while in block-placing mode) WASD to move. Arrow keys to pick up pots, and then again to throw those pots.
Please report any bugs in the comments, and tell me how to recreate them. Most of the dev time on this was trying to fix ONE bug involving the hands. It was a very simple fix, but I didn't see it until like 3 hours of coding :,)
