1 star for including a puzzle that can only be solved by guessing. Using triangulation to solve the Paris puzzle yields an answer that is not accepted by the game. On none of the maps does triangulation actually yield the answer the game accepts. You would think the developers would actually spend time checking their puzzles before submitting their game to the public. But I guess that is too much to expect.
For the developer: To overcome the problem that Polored mentions, you could add a Practice option to each level, which lets you play it without the music, but you would still have to beat the level with music to move forward to the next level.
The rune message (in bastardized, mirrored Latinised Futhark) says Mu Database Studiosime Som. They should've used a different rune for c as per the alphabet, so it would've said Studiocime Com, or studiocime.com (no periods in Runes)
I wanted to give this 5 stars, and I did. Then I came to the newspaper level and changed it to 1 star. Requiring people to play a game by doing something outside the game is a big no-no, and is taught in Game Development 101.
You know it's a good game when greg comments on it. And it truly is a wonderful game. Never thought a simple story about a duck could become such a magnificent game.
