For @kuligs2 , you can drag the screen around now without deselecting a component.
For @MikeCL , a UI pop up first level to explain the objective
For @xyz, a level 2 and a hard level 3. Also made the mouths of most components bend inwards for better emphasis.
For @REVBENT , pop ups for newly introduced components explaining how they work.
Also for @REVBENT and Kuligs2 : I made the Engraver bigger so that the coins don't so easily get stuck
Thanks so much guys for the suggestions. The only thing I didn't tackle that I probably should have is the rotate UI but... we'll see.
