Now this is good! Visual novels are a rare treat. I especially like which character's headspace we occupy, at the start I assumed it would play out like an escape room game, but going from the captor's perspective is a lot more interesting, especially given all the contradictions they present.
Like, I don't really know what Lucio's plan on getting away with this was supposed to be. For a supposedly smart guy, stealing the neighbor's axe to commit the crime seems like a pretty major mistake, and he's bound to get caught immediately. It's also interesting that he wants to meticulously time the murder, but completely improvises the weapon, like he's overthinking some parts and underthinking other parts.
I also wasn't quite sure what the countdown Lucio imposed on himself is supposed to represent, especially since it gets in the way of his own plans. If he follows it to a T, then it guarantees that he's late to the ball, which is interesting. Was he subconsciously trying to sabotage himself? These little mistakes actually strengthen the plot and the character just by blurring the lines on how willing they are to go through with the murder.
I'd like to see some change in the ending if you pick all blue, then switch to red at the last moment, or vice versa, but what's present here for a jam game is an interesting read. Really great job!
