Braille.
One of their biggest mistakes.
For games puzzle, the player must be able to discover it by yourself.
With Braille, you either know it or you don't.
And there are bullshit puzzles like: use Dig.
So, basically: If you know Braille, it's simple. If you don't, google it, then it become simple.
And the worst part is in FRLG, when you actually have to check some other source to complete the game.
