So wolfururu mentioned The Mortuary Assistant in a comment below and that's where my mind went as soon as I saw the premise for this one as well. Unfortunately, if we're going to stick to a video game analogy, the short length and breakneck pace of the VN leaves it feeling more like one level or sequence in a bigger project than something that feels complete and fully developed. I didn't dislike this, but I also think there's a lot of room to further develop plot and characters, as well as presentation here. Breaking it down further:
Implementation of Theme:
Sure, this one meets the ask. We have the folk legend about putting a coin in a corpse's mouth to do some spooky shit to reveal their killer, and said spooky shit does indeed happen after Michelle does the thing. There are a few details that are unclear or unexplained, but for the purposes of this rating criterion, I think we're good to go.
Presentation/Writing:
First off, there is some real quality art here, especially the wolf on the autopsy table and especially especially the first CG at the bar. The sprites look decent too, and while I do wish there was more variation in expressions, I get that producing a lot of assets under jam pressure is tough.
The shifting text box to follow the speaker in dialogue scenes felt interesting and original at first, but lost its appeal and even became a bit distracting as the VN went on. I think it's a neat idea, but maybe it should be saved for specific scenes that best suit it, like the intro scene in the bar where two characters are in one spot, having a straightforward conversation, and the shot is framed so they're each on one side of the screen facing each other so the tennis match dialogue box looks a bit more natural, and then just use standard dialogue styles for other scenes.
Also regarding the dialogue boxes, I'm not sure why Ricardo's name tag for dialogue is just "Iguana" when we know what his name is. Don't know if that was a holdover from a draft that didn't get changed, or just an error.
Sound was noticeably absent for large swaths of the VN, and this is a real killer. The story was a bit underwritten here, which I'll get to in a bit, but generally you can get away with a simple plot and characters in a horror piece as long as the suspense is done well. If you're going to go that route though, you absolutely need visuals and audio to build dread about what's coming next, and that's not consistently present in this VN.
I will reiterate here as I do whenever there's an entry written by a non-native English speaker that writing in translation is extremely difficult and I respect the effort and dedication to get your work out there despite that. That said, there were definitely some parts of the script where things might have been getting lost in translation. While the VN wasn't difficult to get through per se, there were lines that were pretty difficult to parse, and I think that may have contributed to several other commenters (and me too, probably) not fully understanding what you were trying to convey.
Story:
Alright, so the core concept here is pretty straightforward. We have two friends working in a morgue while there's an oppressive regime running things, a jerk soldier shows up with a corpse, one of the friends says "hey I bet that jerk soldier killed this guy", they do a superstition magic trick, it turns out that jerk soldier did kill that guy, and the jerk soldier gets hit by a car for his trouble.
Like I said above, the plot doesn't need to be overly complicated here, but it's pretty thin as is, as are the characters. Jorge and Michelle barely have any distinguishable personality traits other than Jorge being more cautious and less superstitious, maybe, and Damasceno is almost entirely one-note. There's actually a bit of a paradox for me here since we get more of a feeling for what Jorge and Michelle are like from the frame story than the main narrative, but otherwise I feel like the frame story is mostly superfluous. While I want to reinforce that the bar CG is cool as hell, I do wish that some of the time and effort spent on that scene had been reallocated to fleshing out the main narrative. Like, maybe just start in 1973 and give Jorge and Michellle a few more interactions, before, during, and after the haunting, maybe add a few with Ricardo as well. Once the haunting starts, maybe have a few encounters with Damasceno to show how he's slipping and how the relics of his misdeeds are driving him insane.
To touch on those relics a bit more, I think I see the vision here, with each of the objects Jorge finds being something related to Damasceno's actions. The envelope is some sort of bribe, maybe paid to the wolf to keep quiet, and because he didn't "do what he was told", Damasceno's marriage blew up, hence the ring, and the wolf was killed in a similar manner to the horse, who is implied to have also been killed by Damasceno. Damasceno is then killed by a car because that was his way of killing his victims. I can also see the impetus for keeping those details subtle, but I think having a few more scenes with Damasceno present and reacting to things (even if he's cagey or in denial) could make it easier to make those connections, and also just make the setup flow better. Like if the haunting is ostensibly for Damasceno because he's the killer, why is all the evidence being chucked at Jorge, who doesn't know what it means? Maybe if it was Michelle getting that stuff it would make more sense since she at least caused the haunting in the first place, but Jorge doesn't really track for me.
Honestly, I think the best way to have done this story would probably be to cut the frame narrative and have the whole thing from Damasceno's perspective. Have him come in with an air of authority, then have him collapse as he's haunted by his memories and the audience is filled in on what actually happened. Damasceno finding out about what Michelle did could also lead to a secondary conflict there before he eventually meets his poetic demise. I know "aha you've been playing as the bad guy the whole time" is becoming a bit trendy now, but I think that sets up a much more interesting delivery on your premise than what's currently here.
Creativity:
Despite the critiques above, for a second (that's what it says in the VN's outro anyway - I only see one entry on your itch page) attempt this was still pretty decent. There are a lot of good ideas here - the terror of Operation Condor-era (or I guess slightly before then in this case) oppression in South America is underserved in pretty much every genre, let alone furry horror VNs, and I think these stories are absolutely needed in South America's current political climate. I think you have some good horror/thriller instincts and general writing abilities, I'd just want your next project to take those ideas a couple steps further.
Final score of 10 buckets of blood out of 1 new set of tires.
