Maze of Galious Walkthrough

You don't need a map or anything (that just spoils). Just some (non-essential, but rather handy) items are impossible to get (and use even) without having a(n outside) clue. I believe these were originally 'spoiled' by Konami in some magazine, or via the game hints hotline or something? Oh, and a certain essential item is kinda impossible to get w/o a hint as well

The feather will come in handy in exploring the castle.

Then there are these rooms with 'bubbles'... You might figure out what to do there / what's that for (by accident perhaps)

You can find a game manual on archive.org or elsewhere.

Note: there's an MSX2 version coming up (might not be too far away now?)
Note2: an unofficial sequel is in the making.

Of course / indeed we can give hints for that impossible stuff without spoiling anything else :)

Does anyone know more about these 'official' hints Konami released to the public (links to magazines or otherwise)?

Okay, I'm giving this game a shot. I have a question: How do I use the white arrows? It says to move your character. I'm moving. I have them equipped, and nothing happens.

As for how to approach this game, I decided to see how much I can do before entering the first dungeon. This tip also works with just about every single Zelda game.

That's a fair point!

Ofcourse I did. What I meant is more the heavy-on-exploration part. I know a lot of people actually enjoy that.
Let's say, for instance the Ys games, that's just the amount of exploration (labyrinthine maps, crossroads...) that I can suffer.

In that case It would be very beneficial to have a map of the castle.

+1 to what Manuel said. Without the manual, it's almost impossible to know what some items do. And some are key to beating the game. For example, you could get easily stuck in world 2 without the instructions...
