Sokoban with a twist (or two), and timing is everything! Also, the perspective view is quite deceptive at some points. It took me like forever to get how to pass on the second level.
(I have actually an idea for a different kind of Sokoban-ish with a twist game brewing in my head for a few weeks now, but it wouldn't have fitted the theme at all...)
Very cool music as well, and smoothly playing across intermission screens and levels.
