I'm writing this review from the point of view of someone that just experienced for the first time the entirety of Summer Heat as of the v6.0 release. Overall I think the game is nice but it flounders in a couple of key areas. The dev's work ethic is brought into question too as this barely qualifies for a prologue by most VN's standards.
Presentation
Summer Heat's presentation is great at a first glance, it has a clear defined identity and it shows a lot of polish in key areas like the menus, in game UI and overall flare and aesthetics, almost everything comes together except for some hiccups when it comes to the sound and some visual elements which I'll explain later.
Gameplay
Top of the line as far as linear VN's are concerned. So far your choices don't diverge too much (which is a good thing for the development side of things), but there's plenty of interactivity and reactivity peppered throughout the game, a lot of your choices are remembered by the characters and the order that you do certain dialogues/actions matter by the way some scenes play out. It's great because it adds replayability and you can go "oh shit that was not a meaningless choice". I'm torn on the "pick this choice to get closer to x character" but other than that everything else is solid.
Sound
I like the sound effects, there's a lot of variety and off the top of my head I never went "oh, something would've been nice here", I quite enjoy the sound effects during sex scenes too, that combined with the ambience, add to the overall immersion and it makes the game feel natural. There are some issues when it comes with the music and overall sound mixing however. The music is fine, but for the most part it plays too infrequently and although I think silence can make certain scenes more poignant it loses power when you go for long periods of nothing, it's even more jarring when a melody starts playing out of nowhere as you get into an emotional scene. There are issues with the sound mixing too since sometimes the music/sfx would be at the right volume but the next time they played they would be borderline inaudible.
Visual Art
Renders are top of the line as far as 3d models go, but I have a couple of issues. There's an overuse of gaussian blur that looks out of place at best or it completely butchers a scene in places where it wouldn't make sense to have it, I know the dev is going for a "professional photograph look" but it would be nice if it was used more sparingly. Certain characters' proportions looked off to me in some places particularly early on but they may have been adjusted for later versions.
Writing
When it comes to writing in this game I'm torn between really liking some elements while disliking many
others.
Let's start with the good:
I enjoy the overall eerie vibe and secrecy in the game, it's almost Lynchian in a way, I've glanced at a couple of reviews mentioning how there's no plot so to speak but I think that if done properly once the ball gets rolling the story will make sense when it gets there (if it gets there), which is why I prefaced my review by mentioning how this feels more like an unfinished prologue. If you think about it most slasher/horror films start with something boring like a lame party or visiting a creepy grandma then things suddenly start happening and I can see summer heat doing something similar with its plot. With that being said, you can have all the set up you want but if there's no payoff then this becomes more of a frustration than anything
For the bad side of the writing well...:
So far, after 2.5 years of dev time 1.5 ingame days have passed, on the same day you make a couple of trips with Miller to the same strip mall for some reason, get tangled up with most LI's and a couple of side characters, do several photoshoots, go to art class, go to PE class in the woods, play around, watch a movie, get wasted in a strip club, get reprimanded by your art teacher/summer camp leader, fool around with a girl you met earlier, fool around with your childhood friend, etc. This is in a weird balance where a lot of things are happening individually with each character but not enough is happening overall with the world and the environment that you inhabit. I have a couple of issues with poor characterization too, the story doesn't do enough to justify most of the intimate encounters that happen within the game except for maybe Eve which is antisocial (in the "lets go burn a church" sense of the word) and Mia which clearly has a lot of personal history with the MC I'm willing to bet they probably took each others virginities too so their hookup makes some sense
Porn
I'll admit, the 3/4 sexual scenes that are in the game are really hot, devs have a good eye for eroticism and the escalation that happens (within the scene) is great
You just know the leg locking creampie sex scene with Bree is going to be great, however I feel like the sex scenes as of now are misplaced or just put in to appease the Patreons to avoid the "no sex" tag, the scene with the car lady feels way out of place since the game doesn't present itself as pure smut, the scene with the mafia boss daughter is similar despite having some possible plot relevance but the problem there is that too much happens within a single night for it to be believable. And although Mia's scenes are great they feel more like a warm up for the real thing that may not even come within the next two/three years (if ever). I don't know who is the audience for this, there's not enough writing or set up for the slow burn crowd and not enough sex for the ctrlskip chronic masturbators
Let's do some math, last update (v0.5) was on October 2023, 10 months ago, according to the changelog the devs did:
6 renders per day and 65 words per day at a 0.04wpm rate, I understand that dev time is not all just that but you compare this to other projects and you can clearly see how slow it's going not to mention how they are inflating their numbers just by looking at the files with unren, there are no 100 new sfx/music/ambience they are just counting every time they implement something like this on the script, might as well count scene transitions at that point.
I wanted to give this game 1 star because frankly it looks like yet another tale of "dev gets lazy as soon as he gets $1000/month on patreon", in 2.5 years 1.5 in game days have passed, there's a new 3 day deadline which means by 2029 we'll have something actually worth playing.
You hate to see it but at this rate the game is either getting abandoned or getting rushed to a completed state in an unsatisfactory manner, I didn't get anything out of it when I played the v0.6 release, I'm going to wait at least three more years or until it gets completed/abandoned. I recommend you do the same.
