I think I'm going to name the puzzle game Home Base, thanks to S-Chuck's name suggestion. Technically, you have to get each block to its home base, so the name, though it could be misleading, fits nicely.
Here's a screenshot showing the translucent background as well as the smoke effect when a block is parked home.

I'm also collabing on a project with another eo member, lending a hand in the graphics department.
