Half-Minute Hero designer Kotaro Yoshida is making another twist on classic RPG tropes, with the announcement of "100 Turn Hero." It's due to hit iOS devices in Japan on January 17. No US plans have been announced yet.
Famitsu (via Siliconera) gave a look at the game, which utilizes the same pixel-art style employed in Half-Minute Hero. Details are vague on just how the game will work, but the title and some of the information from Famitsu would seem to indicate that you'll be restricted to 100 attacks to defeat the enemies. Rather than quickly rushing through gobs of badguys like the prior game, this one might require a more thoughtful approach to conserve your moves.
