Konami throws its hat into the DSiWare ring with Reflection, a puzzle platformer from Intrinsic Games that has the player controlling one character twice over.
Reflection stars Kirra, a young adventurer tasked with retrieving the pieces of a broken magical mirror that has ripped reality in two. Kirra herself is split in two as well, so the player must navigate the world via two both the top and bottom screens on the DSi, using the same set of controls to solve puzzles that require both the normal and upside-down versions of the heroine.
While we can't tell much about the gameplay from these screenshots, one thing is certain - it has to be better than a clock. There's no release date, but once we have one the DSi has plenty of options for keeping track of that sort of thing.
