Grasshopper is going to reveal Frog Minutes, their first iOS game in support of Japanese relief efforts, at their March 30th Grasstream 2 event. We know nothing about the game outside of its logo, as seen on Japanese gaming magazine Famitsu's website, and that all of the proceeds for the game will go to the Red Cross in support of the Japanese earthquake victims.
