I really like the style, concept and overall presentation... but the controls were a little hard to get used to. Even after telling my brain that left was diagonal up I still couldn't really do it.
I think shifting the controls to match the isometric view would have helped a bunch because it was hard for me to wrap my brain around it.
Oh and I had a bug where I lost control of both cubes a few times. Usually happened when I collided with another object while detaching. Resetting fixed it but still thought you should know.
Still an enjoyable game though! Liked it a lot.
