Controls:
Despite Steam saying it requires a controller to play, you can actually use the keyboard. Big brother is WASD and Space; little brother is arrow keys and right Ctrl; left and right Shift move the camera. You CANNOT play on more than one controller without using outside programs - this makes local co-op a little uncomfortable, but still doable. Solo controls make sense and seem decently comfortable.

Visuals and Audio:
The visuals are well done. Everything is detailed and there are many beautiful landscapes. Each setting has a solid atmosphere to it. Audio adds to this effect. Characters speak in nonsense but it seems like at least a little work was put in to making it sound like it could actually be a system of communication, so overall it's charming. There is a lot of use of body language. Physics are mostly smooth, but some animations such as climbing don't have transitions and you can do little dances.

Gameplay:
I played the whole game co-op for the most part, so I can't comment on solo play until I go through it again. It works well as a co-op game, especially using the keyboard. It's fun to cooperate on the puzzles.

The game is extremely linear and the puzzles are all pretty simple. It took three hours to finish co-op, solo wouldn't be more than four. There is replayability with the included achievements, but there are no choices to make or alternate paths to take.

I only experienced one glitch where the big brother got stuck in some terrain near the beginning of a game, but it was right after a checkpoint so I didn't lose any time.

You can pretty much split the game into two halves. The first half is charming and great fun to play. You can interact with NPCs and see the two brothers' personalities and skills. Working together to solve puzzles and clear obstacles is a rewarding experience, and there are frequently new mechanics to enjoy. The second half makes this game harder to recommend, starting I believe after you complete the tower area. It's a lot darker in theme and the end of the game has very little payoff. My co-op partner was extremely put off and disappointed with this part of the game. You have to bury your own darn brother under the tree of life, and he doesn't even resurrect afterwards. But hey, if you have a thing for arachnid women, you might enjoy this part.

Recommendation:
Given the short play time, I would only recommend buying this on a good sale. After that, you may have a lot more enjoyable experience if you stop as soon as you finish the tower. But overall, the game looks great and is fun to play. There is a little replayability, but this is lessened by the linearity.
