Song of Farca plays sort of like a visual novel with puzzle gameplay elements. As a private investigator under house arrest, living in this cool city on a Mediterranean island, we solve a series of cases loosely connected by recurring characters while working remotely all the time. Fortunately, she has access to technologies that allow her to hack everything out there in the blink of an eye (don't ask how it works) and even has this super AI helper which she wrote herself from scratch! Future, man.
The main minigame is hacking security cameras and drones to get evidence and intel. This gets slightly more complex as you progress, but the only really difficult part of the game might be figuring out passwords, which involves sometimes rather abstract puzzles (but there is a hint system). Collected data is then used to construct arguments during conversations - which is impossible to fail since there is an infinite number of retries until you get it right. The only irreversible parts are occasional choices, which may affect the story in a minor way, although most choices are rather illusory. For example, in early cases, the game forces the player to incriminate basically a random person out of three, based on a "hunch" due to a lack of hard evidence (great detective work indeed...), or choose to make or not make a deal with a blackmailer - but then it's mostly meaningless anyway, even when subplots return later. For the most part, it's linear and only a few decisions matter.
I found the protagonist likable and the storytelling quite involving, each chapter/case being like a separate episode of a TV series, but with this bigger picture constantly forming in the background and culminating in an intense finale. It's really fairly nicely put together, which is important because with repetitive and simplistic gameplay, it's mostly the story that keeps the player interested.
The dialogs, I assume, weren't written by native English speakers because they feel awkward at times.
The music is pretty good and fitting, but it could have more tracks, though.
While it's not perfect, I enjoyed it very much.
