With concept art and a logo that look like they were ripped straight out of a Mirror's Edge anime fansite, it's not surprising that Konami's first DSiWare title Reflection is all about the gameplay and not the graphics. The game features an extremely innovative use of the DSi's second screen as a literal reflection (get it?) of the game, turning an otherwise pedestrian platformer into a challenging puzzler.
You play as Kirra, a thief for hire who has been tasked with retrieving an ancient mirror from some similarly ancient ruins. When she finds the mirror, it does what all ancient mirrors do: it breaks. And in doing so, the mirror shatters her reality as well. She now has to reassemble the mirror if there is any hope of restoring her world, and she does this by traveling through both her world and the mirror world, reflected in the DSi's bottom screen.
