DSiWare: Pop+ Solo, 500 Nintendo Points
From hilariously-named developer Nnooo, Pop returns in the form of DSiWare. Several play modes await you, including the standard Adventure (now with brand-new obstacles), Normal and Advanced modes, along with Bonus mode for tackling bonus stages, and Chill mode for relaxing and popping bubbles. You can even create your own challenges in Challenge mode.
WiiWare: Mr. Driller W, 800 Nintendo Points
Experience the exciting world of underground drilling with Mr. Driller W. This action/puzzle game has you drilling through colored blocks in "20 varied stages and missions" while keeping an eye on your oxygen level. This newest addition offers varying degrees of difficulty and a tutorial for beginners, as well as numerous fun characters.
SNES: Super Empire Strikes Back, 800 Nintendo Points
The saga continues in this SNES sequel. No gameplay details were given, so they are presumably similar to those of Super Star Wars, just in the locations showcased in The Empire Strikes Back.
Not as much going on this week, though I hear good things about the Mr. Driller franchise in general.
