'Second Chance' is your standard isekai/'died and born in another world' kinda story. It's very straight forward in how it sets itself up, and I don't hate how non-descript and generic it comes off. In a way, it has it's own stylization to it that makes it very easy to understand visually what is going on. I should also point out that this entry was completed in seven days, so while that doesn't look good for time management aspect, it's still impressive what could be put together in such a short amount of time.
The story itself is only the introduction and the first scene of what would be a larger visual novel story. The first scene is a black void scene where [insert character name here] has gone and drowned himself because of non-descript personal issues that made him give up on life. He's approached by the "God of Curses" in the void, and gets reborn/re-materialized as a dog person in this new world of magic. Fun to have the human to furry wish fulfillment happen right off the bat. He wakes up to a very shirtless wolf who has found him in the forest and tells him of his quest to gather the four non-descript heroes of the non-descript prophecy so they can take down the non-descript evil brother of the benevolent king after the non-descript prince had gone missing. They talk a little bit, and then you fall asleep. I joke about the non-descript stuff, since it sort of evolves into it's own style the more it's used, color coordination for magic styles, and what not.
The presentation I think is serviceable. There's some really strong direction with the bold symbols in the void, the bright saturated magic colors, and even the character designs being simple but distinct. The music works well enough, and there's a lot of text timing to add impact while reading. The writing does need a lot of help though. Plenty of typos, awkward grammar from mixing of the tenses in words, and some weird sentence structures. I wonder if this might be an ESL thing or just no time for proofreading, so I can understand that element.
The folklore aspect in this entry is represented by the generic prophecy that is the main plot thread in the story, and I guess it serves it's function to give the wolf character a reason to go on this journey. The bits that really made me like this entry were the little self-aware jokes, that could almost have this function as a parody, if I knew it wasn't trying to be a parody, it was one of those 'look to the camera tell joke' moments. "Ah... you're finally awake." being a recognizable meme and the out of left field "want to see my dick?" and "what is this a furry visual novel?" give this visual novel a weird charm to it that is a breath of fresh air from trying to take itself too seriously. That being said, it is just another isekai that doesn't seem to be trying anything particularly different, almost paint by numbers.
I would say that what this visual novel needs is direction, because it's hard to gauge just how serious you want this visual novel to be. If you're going the route of making it more serious and straight-forward, it's going to need a lot of outlining and a lot of internal consistency. Stuff like figuring out the main character's motivation. He's getting a second chance, at what? To lead a regular life? To feel like he's doing something good? To make up for a mistake in his past? Why would he go on this seemingly dangerous journey in a new world with this wolf to fulfill a prophecy he has no investment in? These are questions that you'll have to think about as you continue to develop this story. If you want to go the comedy and parody route, you'd also need to have internally consistent lore. Just how aware is the main guy of isekai and visual novel tropes? Does he know he's in an isekai? Just how ridiculous are you going to make the characters?
Overall, I noticed that his is a first time build for this author, and honestly, I love the gumption. It's got a strong bold art style to it, and there's potential for it to grow, but that's what's there, potential. It's a bit hard for me to praise what hasn't been made yet. Another thing I would try to work on is time management, goal setting and establishing scope. A big pitfall of VNs is having too lofty and grand an idea that it either never gets made, or remains in an unfinished state. Set a time limit and a goal for doing updates or chapters. If it takes you a week to do this intro, try to set a goal of one to two months to finish the first chapter which will get the characters to the village and meet the healer. Outline how many major 'things' should happen for your story. Figure out what characters should show up when and where, design the characters, design the villains, come up with a cool conflict. That's really all the fun of making these, and I hope that you continue to have fun making it.
