Try to play Time Hollow
We still think it's worth clicking through the reams of text to experience this demo, if only to have a look at the wonderful presentation of the game. The backgrounds are beautiful, and the music is lush (if a bit overwrought.) You'll also see a short cutscene or two showing the time-travel-pen gimmick.
This thing looks to have had money poured into it, so we wouldn't be too surprised to see Konami selling it worldwide.
