I tried really hard to like this game, and recommend it, but it didn't happen.
The Journey Down is a point-and-click adventure game with very unique visual style, above-avarage music, fine voiceacting, and a silly storyline with dumbest puzzles ever imaginable. I usually don't look for difficulty in point-and-click adventure games, since I found story to be the most important thing to consider, but these puzzles are beyond any measurement of difficulty. I mean, Broken Age for example, also had pretty easy puzzles, but they made sense, progressed the story in one way or another, and they required some kind of thinking nonetheless. In The Journey Down, puzzles are like "There's a thirsty guy over here, there's a glass over there, and there's a water tap right there. Now you click them in order.", and they have no contribution to story whatsoever. By the way, you are a reggie guy who speaks five times slower than an avarage person, reviewing literally each and every action you do. Game consistently tries to be funny, especially with accents, but they are flat-out boring, with nothing happening outside. And that's about it.
Although it's not the worst point-and-click adventure game ever, there are so many amazing point-and-click games to be played like Monkey Island series, The Longest Journey series, Syberia series, Discworld, Full Thortle, Broken Sword series, and Broken Age, that The Journey Down is not even a competitor.
One last thing, if you can compare this game with Grim Fandango, you are clearly out of your mind.
