Ngmoco:) announced Rolando 2 for the iPhone this June and Rolando 3 will follow nine months later. Their other game in development, Star Defence, should be out "soon."
Rolando is basically Loco Roco, only when you tilt the iPhone, it actually has an effect on the rolly-polly character's movement. The music may not be as infectious, and the characters not as a cute, but it's been a pretty popular game on the iPhone and it gets several free levels with regular updates from ngcomo:).
Star Defence is a tower defense-style game where you manage a small planet and defend it from invading tripods. Not much has been said about the title beyond the sporadic blog post on ngcomo:)'s site, but you can check out a video of it in action here.
Rolando 2: Quest for the Golden Orchid will follow the same format as the first game, starting with four worlds and 26 levels at launch and getting 20 new levels via four free updates for the game. The new level releases will lead up to Rolando 3 sometime later in 2009 or early 2010 if Rolando 2 doesn't make its June launch.
"In eleven months, we will have released 12 worlds, 149 levels, 40+ hours of gameplay for less than the cost of a single DS or PSP game," said ngmoco:) founder Neil Young.
Damn. Maybe it's time I shell out for an iPhone.
