About Lock & Key: A Magical Girl Mystery

What does it mean to be a magical girl?

This is the question at the heart of Lock and Key, a magical mystery visual novel set in a world shaped by your interpretation of the magical girl genre.
Sherri and Kealey Cohen, now a married couple in their late 20s, left the title of magical girls behind them over a decade ago. Now on the verge of losing their powers and entering a life of true normalcy, a string of unexplainable murders forces them to come out of retirement for one last adventure. Together with Nina, their old friend, and Ruby, a new protégé, Sherri and Kealey will have to face a mystery connected both to their past and future. In the world of Lock and Key, the player shapes their path... and more importantly, determines where that path will end.
Since this is a visual novel, you the reader are in control! The decisions you make in-game will determine the outcome of the story, and the fates of the characters in it.

An exceptional game. There is one bug, however: every time I try to get anything other than the happy ending, a bug called "my heart wouldn't take it" appear, preventing me from progressing. 10/10

This is a good yuri visual novel. It has great art and character designs. I especially love that it focuses on a 30-year-old married couple - not something you see every day. Nor is the religious Jewish and trans representation. It makes this story feel really novel because of those perspectives - these aren't the same old characters and situations we've seen 100 times. However, I think this story really had the potential to be great and not just good. The story it tells feels like it should be epic and emotional - it's about magical girls saving the world after all. But the game's lightning quick pacing keeps you from connecting as deeply with the characters. The mystery is also very obvious and revealed very quickly. It feels like the game was intended to originally be much larger and greater in scope. For example, the game's "Data" feature updates a ton in the first hour, but only shows up once after that and ultimately feels superfluous since there is only one case in the game. In the end, this is a story that probably needed 10+ hours to be at it's best - both for the characters and it's plot. Despite these shortcomings, I do think it's worth reading, especially if you l…

I really had a great time with Lock & Key! Despite its shorter length compared to the other VNs by Studio Elan, it's still a fun time with a lot of moments that made me giggles, made me scream WHAT THE ♥♥♥♥ so many times, and made me cry. Sherri and Kealey are great protagonists as they embody a very grounded experience of a lesbian couple who has been together for over a decade. They bounce off with each other really well, they have great communications with each other, and most importantly they trust each other when facing internal struggles and the murder mystery. Ruby is a really great newcomer character and sort of acts like a social commentary on our hope towards the younger generations. She's hot-headed, insecure, naive, and tech-savvy, but most importantly her heart is in the right place. It's a good trait that can lean her towards the good or bad endings very naturally (also Jude deserves more screen time and they both need to date each other uwu) Nina is a very complex character to discuss because of how well-written she is. It'd take an entire day to discuss everything about her. All I can say for her is that it's always an exciting moment with her, and... #STANNINA …

Very good game! The story and relationships are strong and has many unexpected plot twits. I was pleasantly surprised as it was better than my original expectation starting the game. The art style is super cute and whimsical.

This is Studio Elan at their best. When I saw that it was going to be magical-girl themed, I was worried it might be a little too cliché, but they do a great job at mocking the genre and making this feel grounded in reality even though it's a fantasy story. There are maybe two or three little contradictions here and there (for instance, in one scene they say [spoiler]Elle's family still believes she's alive somewhere, later they say they reported the body to the police[/spoiler]). I also spotted one mixup where the good dialog was showing in the bad path and vice versa ([spoiler]there's a scene that says "as for Ruby, she's..." and goes on to either say she's doing well leading the magical girls or that they're worried about how she's heartless when killing, but the first prompt is showing when you have low affinity with Ruby instead of high affinity, and the second is showing for high affinity[/spoiler]). But honestly, for a story this big, the plot remains surprisingly consistent. Which is hard. I write literature, and I know how hard that can be. Anyway, solid story. 10/10. Studio Elan is my favourite VN developer and this is one of their best works.

I really enjoyed Lock and Key as a fan of Studio Elan vns already. In terms of Studio Elan games I found it to be fairly more simple and short then most of their other offerings, but still lengthy enough to tell its story. One of the big things about this one I really liked was the main couple of Sherri and Kealey already being married. I loved every scene of them being romantic with each other, it's so nice seeing them have a stable relationship without any of that will they won't they/ /focus on tension in their relationship. As much as those things can be enjoyable, it was so refreshing to see the pure love of the two here, especially since it allows more focus on the plot threads of the murder and training of the next generation. The magical girl plot was really well done. I love seeing how the aging magical girls try to find their footing now that their magic is fading.I also find it a nice juxtaposition with Ruby trying to find her place as a magical girl. Without spoiling I do wish there was more time in the early segments just because I feel the reveal of the murderer came way too early. While I like how the rest of the game deals with the fallout, it really does not fe…
