About the gameplay, I decided to hide every buttons at screen, so the whole viewport is dedicated to the game. I tried Phantom Hourglass on DS, but I found it hard to play, especially for making Link rolling ! (There's no roll with Zildo !)
In my version, which is temporary, you touch the screen anywhere and the move you do with your finger give the direction for Zildo. As long as you hold your move, Zildo keeps moving. About buttons, the right half of the screen is divided into two regions : top for action (talk, pick up, skip dialog...) and bottom for weapon. To get into Zildo's inventory, just touch him.
I find it not too bad, for now, but I need your impressions, because gameplay is very important in my opinion. Regardless of the graphics quality, sound, or whatever, a player can have a really bad feeling about a game just because the gameplay is painful.
