Got a New Nintendo 3DS

Today, I studied English for 6 hours on the internet learning site of my university.

I was happy to earn high score on that site, and I bought a New Nintendo 3DS as a reward for myself.

So I bought "The Legend of Zelda: Ocarina of Time 3D", and played it.

I was impressed with 3D viewing, however, it was really tiring to keep playing.

About after 30 minutes, headache occurred and I closed the 3DS gently.
