The star of Bikkuri! Dokkiri! Majou no Pen is a little witch named Saatan who wields a magic pen, which looks remarkably like the DS stylus. She has the ability to create over 120 items. You simply trace and color the item on the touch screen, and it will appear a designated location in the game. Some items that have appeared in released screenshots include a house and a tree.
You aren’t just creating items for yourself though. You’re doing it to help people! The citizens in the game world all have requests — items that they want or need. If you take the time to assist them and draw stuff, they’ll like you more and presumably good things will happen.
Since it’s rated CERO A (all ages) and the screenshots don’t seem laden with kanji, I’m guessing kids are the target audience. It looks adorable and has an interesting premise though. So far, there’s no definite release date. Atlus has a good working relationship with Global A. Maybe they’ll take notice of Bikkuri! Dokkiri! Mahou no Pen and bring it over.
