Making this Post a placeholder. I will fill in a few parts from the impressions of the gamer which I will translate from german to english.
Here are a few translated words from the impressions (it's more an interpretation, an exact translation costs a lot of more work). Sadly, he told nothing about the magic or stamina bar, whatever it is. He also told, this temple might only serve as a demo, not featured the exact same way in the final game. The Press Event took place at the Nintendo of Europe subsidiary in Frankfurt.
The demo played with heights. Even the temple reached far into the clouds. Link could not pass through all the doors. Than he became some sort of chalk-drawing. With this technique, he was able to reach restricted areas.
At the top of the tower, an old enemy awaits us. The fight is similar to the one we fought in A Link to the Past. But now, it is even more trickier.
In the Demo, we've met many known enemies from A Link to the Past. The same goes for the items like the Hammer, the bricks and these turtle-like enemies. All that felt familiar with the Shadow Temple from the SNES classic.
The gameplay felt very nostalgic, but the new features also fits perfect in this new title. The view is Top Down but every detail is rendered in 3D. This style is simmilar to The New Super Mario. Bros series. I loved the Skyward Sword style, so it is a bit unfortunate Nintendo said Goodbye to this artistic style. But anyway, Zelda 3DS looks just beautiful.
Verdict:
A new Zelda! Yeah! After Ocarina of Time, the Top Down view was doomed, but Nintendo surpised us like always. We had a lot of fun in this first temple, and even in this state of production, the new game mechanics convinced us. Now, the most important part is the story. So far, no word were mentioned when it comes to the plot. We are very excited and can't wait for the complete game.
