Link Twin

A simple, yet delightful puzzle game based around the concept of moving two characters simultaneously.
The good (+), the bad (-) and the indifferent(~):
+ Smooth learning curve, each new mechanic is well introduced and demonstrated.
+ Effort has clearly been put into creating varied and interesting level designs.
+ Very pleasing visiual athetic and music.
+ Solving a level in the minimum number of moves is most satisfying, but not essential.
+ In game solutions are available (though limited in number).
+ Good amount of puzzling for the cost (esp. on sale).
- The level selection screen seems a little buggy when switching between different worlds.
~ The initial levels may be too easy for some, but the difficulty improves for the second half (the first 60 levels took me 1 hr, but the next 20 took a further hour).
~ Controlling two (or more) characters simultaneously is not a brand new mechanic ("I and Me" and "The Swapper" are two games a similar mechanic), but the grid base implementation and minimizing the number of moves is new.
Overall, a worthy experience.

A pretty little puzzler with dual sokoban style gameplay. The A/V is relaxing and makes for an enjoyable experience. I appreciated the minimal move approach and tight board design.

Cute, but forgettable variant of sokoban in which you control two characters, moving as one, and with the outer borders removed. There are also a couple of additions like teleporting between separate boards and a rudimentary story. The puzzles slowly increase in difficulty. Some replayability if you want to do things more efficiently and earn more stars. The two main characters, Tom & Lily, are adorable.
There is a spoil system if you get really stuck, but you can use it only a limited number of times, and it does right out tell you the solution, so beware of that before you use it. For the more challenging puzzles you will have to think ahead any number of steps, but actions can be undone or reset at any time, so you don’t have to worry about anything being final.
The only real annoyance I had was when replaying to get more stars: The way level select works forces me to flip through all chapters every time I want to switch to another level. I also had to wait for the level select menu animation to finish every time before any interaction was possible, which made the chapter flipping even more annoying.
Final thoughts:
Link Twin is a moderately challenging puzzle game with a stylish look, intuitive controls, and well executed mechanics. The characters you control are adorable, but the story as a whole didn’t matter much — as perhaps expected from a game meant only as a casual distraction. It was nice while it lasted, but forgettable once it ended.
Full review:

Very cute puzzler!
The levels become quite a brain tease in later chapters.
Recommended!

cute little brain tease with smooth difficulty curve and a limited and well design hint system.

Cute and simple puzzle game. Worth the price.
Play it if you have some time to loose and if you are a fan of this genre.

Nice, soft, sweet mood.
Easy puzzles at start. Getting difficult over time.
Relaxed progress, no hardcore puzzles.
Good for half an hour after work.
