TBH I feel you kind of have to lower your standards when it comes to porn games. Most, if not all, of the ones backed by substantial production teams tend to mostly be cookie cutter slice of life VNs consisting of still cg h-scenes that kind of just blend into one another and maybe the latest copypaste job made by Illusion/Illgames.
The rest are, TBH, allot of the slop being posted in these forums; games like Cloud Meadow that feel more incomplete than this game does and is probably never going to have a "full" launch like this did because the patreon money they get from just doing hotfix patches every month is basically giving them all the money they need from doing almost nothing. The glorified Visual Novels made in RPG Maker despite the fact nothing is really done that really justifies the choice of engine. The games that use those horrifically uncanny stock XLNara models or outright stolen porn gifs/pngs for their slop VNs. That's not even mentioning the ones that are almost unplayable.
Only a few half decent porn games manage to get finished every year and half the time you have to be able to tolerate the more niche kinks the dev(s) may focus on that you find cringe.
To be honest, the story could have concluded with the boss of the third stage and the game would still feel like it has the content quantity of an average h-game. If the game didn't hype the players up for a bonus level after beating the game in hard difficulty only for it to be a terribly coded superboss with no real h-scenes to unlock from fighting them and changed the narrative so that things felt a bit more conclusive at the end, with maybe a little tease at a potential sequel if they really wanted to, I feel allot of the complaints would have dissipated.
There was also the issue that the dev basically released what would end up being 95% of the whole game as a crowd funding bonus. I think that if the dev kept maybe at least the third level under wraps, people here would have felt less disappointed.
Overall, I just find it a miracle that this game is even moderately playable and has a good amount of quality, animated h-scenes.
I'm not even going to comment on everything you wrote, but i feel like people have a lot of unjustified hate towards RPG maker games in general. The problem here isn't that RPG maker is somehow janky, crappy program made for children to play with, but rather something that gives you a lot of possibilities even with the default features, but most people don't really know how to use said features let alone to use or make custom scripts where all the real deal is at.
The fact that western devs make really crappy, low effort "games" with it doesn't help either, although there is plenty of that on the japanese side of things as well just not as much. People liking stuff made by Acerola (the most crappy japanese H circle) is something i can't wrap my head around no matter how i might try, and i consider their games the bottom of the barrel tier, the low effort crap that is the equivalent to crap western games using poser models and such, but also badly made and designed slop like Roundscape Ardorevia for example.
I'm really daring someone to tell me that anything made by some western dev is somehow as good as something like Eclipse knight saga.
Yours for example it's a good one, you have a better argument than others that don't even say things like how to make it look or be better, just throwing hate on the things they didn't like being really annoying to read and yes, probably I'm trying to defend them because one of them is my friend and it isn't here to respond anyone or have any possible defense or solve many other doubts. Constructive criticism is always welcome, but if you only say what could be bad for you( or in a more general way if more people say it) and don't take into account what is good to, there's no balance and that's not helping at all either. I'm the first who tries mostly of giving them more ideas or letting them know if something could be out of place and for that I probably took I a bit personally too, because more or less I'm a bit involved in the project too lending a hand ✋.
I feel like i shouldn't even try to have a discussion with you, but at this point you are just full of it to a ridiculous degree. Nobody here was shitting on the game just for the sake of shitting on it, but rather because of the fact that the game shouldn't have been released in the state it's in to begin with.
If you want details i wrote plenty of that in my previous posts in this thread, but i doubt you even bothered to read any of it instead choosing to shit on people who tried to give constructive criticism. Irony much, lol...
As for other things which i didn't write about, well there's plenty of that as well. For starters the fact that there are places in the game where you should be able to get to later on but you can't, because the double jump ability which i assume was planned but was cut out and left for a sequel just isn't there.
Bugs wise i experienced everything from my money and diamond thingies for upgrades disappearing, doubling in number or even going into the negative values on loading the game often bricking my saves permanently because the game sometimes autosaves even over the manual save slots. At some points sena would even get stuck in terrain thus making me have to replay whole sections again. These are just some examples of things that shouldn't happen in any game ever, and this being an indy hentai game isn't an excuse.
Also sylvanus, fuck that guy. Beating him isn't really based on skill but rather on pure luck. If he pulls the most bullshit of nondirectional random bullet patterns out of his ass welp you're toast because sena isn't agile enough to pull of danmaku style grazing in a game that wasn't meant to be a bullet hell in the first place. If he goes with the more directional lasers and such then he is toast instead. What i mean is that he isn't really difficult, he's just annoying and fighting him takes way more time than it rightly should.
And no, i don't need to git gud, i can 1CC all of the touhou games on lunatic difficulty (even the EoSD), and you don't get any more "gud" than that.
To conclude, what i in particular am mad about is that this game has some really good H content, some solid gameplay ideas and a lot of untapped potential, but it is missing a lot of what i can only presume was planned before release.
