Wake the Royalty
Everyone is sleeping in the kingdom. Wake up the royal family! Wake the Royalty is Eugene Karataev's sequel to Wake Up the Box, with a pleasant, hypnotic tune by ImperfectDisciple accompanying it. 25 levels in all, this iteration doesn't really bring anything new to the table, but it's still a fun little diversion. The "boxes" you're waking up this time are actually various shapes (circles, triangles, squares, etc.) with legs and crowns — and perhaps a bit of hair — but the general idea is still the same: jar them enough (or hit them, or launch them off the screen) to wake them up. The backgrounds are still pretty bare (and the same from level to level), but the graphical quality seems to have improved a little bit.

If you're looking for a good phuzzle to waste a bit of time, look no further. (Unless you've already beaten it, in which case, go right ahead.)
