I uploaded controls revision. Now it should have gamepad support (I haven't managed to test it yet, unfortunately I don't have gamepad).
However I have mouse, so I added left mouse button click as alternative action input and I tested it. Cursor position still doesn't matter and target detection works the same as it worked before, but now you can build or chop with LBM instead of SPACEBAR. Could you please try it?
I made it as a hotfix so I haven't made fullrelease with release notes
