As far as Deathsmiles developer Cave is concerned,
Microsoft's Windows Phone 7 platform can go to hell. Bullet-hell, that is! Makoto Asada,
head of Cave's Game Development Department, has announced via dev-blog that the company is currently developing a shooter for Microsoft's burgeoning smartphone OS.
Beyond the fact that development is somewhere between 20 and 30 percent complete, details are scarce. No screenshots or other information have been given, though the announcement refers to the game as an original title, which more than likely means it won't be a port of Cave's recent Deathsmiles release for iOS (above). It's also safe to assume that the game will be bewilderingly difficult.
