Thanks!

You're right, I should make a "security confimration" before exiting the game. I'll put it on my to-do list.

I don't think the menu rotation speed can depend on the system, it's framerate-compensated (MY.PAN += 30 * MY._Drehrichtung * TIME).
Just don't hold down the button until you reached the object you want to reach, because it'll rotate to the next one automatically after you hit it once.

In Secret of Mana weapons and armor rings are made the same. The reason is quite easy:
You have to change weapons much more often than armoy.
If armory was part of the main menu it was to big to roll through, thus therfore armory is collected in a sub-menu.

I don't exactly know what mistakes, some things are my... "personal style of writing" when I don't write texts for the university or something like that.
For example "sz" or "ss" instead of "ß" or "ae" instead of "ä".

After the story part on the ship there are only ~two litte quests to solve in the area of Benezos, but there you can play with all the technical features like different kinds of weapons against the enemies, charging attacks, casting spells, using skills, evading attack, stunning enemies, playing around with different character settings at the Trainer NPC ect.
