When I started the game, I started in the Mii Plaza. lol (I like the music, its relaxing and quirky at the same time~ definitely has Bob's sock vibes).
Pretty simple game, that offers a nice little amount of challenges through achievements. This is a unique memory matching type game. if you are someone that likes memory matching games, this is definitely worth playing. This has a solid execution. I really like (though it is irritating) that the cat pushes the socks around, this keeps you on your toes (lol) causing you to rememorize something which had been moved or force you to rediscovery its new placement because you hadn't noticed it being displaced from where you thought to remember where it was going to be).
There are things you could add if you wanted to be extra for visual feedback, like pulsing the scale of the socks that you have under your selection but the red circle does this job. Or even when the cat meows and starts chasing you, just to show it is chasing versus wandering, you could add a trail effect to it. Just small visual cues could spice it up some more and only because the meow signifies the chase effect, you don't know how long it lasts until the cats just starts wandering around again (which is fine).
The description of the socks was very entertaining... I ended up being like... freakin' Bob.... lol
I played through each difficulty and unlocked 4 of the 10 achievements. So there is a lot of replay value if you are a completionist. Solid game, doesn't do anything complicated and has its own balance through its mechanic. Its theme is solid. Has an entertaining story where my imagination says, hey you can build other games from this set up. Like... I would like to know more and see this gnome kingdom... XD
Maybe consider starting the cat's spawn position outside of a padded range of the player's position because the cat can spawn in front of the player and cause a game over in the first few seconds if you don't move right away and or if you happen to be reading the prompt. But since there is no huge consequence for defeat, this isn't a huge issue~ just a possible scenario that others may encounter, which did happen to me. I died right away and kept resetting only to realize the cat was just in front of me and hit me when the game started. But it happened 3 times in a row when i was restarting the level with my first play through of the easy difficulty.
