Time Hollow hands-on at Siliconera.

"You can’t just walk up and play Time Hollow at Tokyo Game Show. Konami has prospective players wait in a line, walk into a foggy room with a few green lights to see the concept trailer and then you can play the game. The whole dog and pony show ate up about 45 minutes of time, but it was worth it.

The demo begins with an anime introduction and then you step into the shoes of Horo Tokio who is presently in school and briefly explains about that he has this mysterious hollow pen that allows him to make holes into time. Horo talks to two of his classmates about the previous day and the chat is saved as a flashback. Flashbacks are key events that let Horo use the hollow pen to enter back in time and change the past."
