I've reviewed your last game "No Help No Hope"... Sadly, I'm afraid my review now is going to be a near-exact copy of the same points than last time. I see nearly no improvement from last time.
The music is still nice, the visual are still cool, and the story still doesn't engage me enough to make it an enjoyable game.
I tried finding the courage to read the entire story, but roughly two thirds in, I lost patience and started fast-forwarding until reaching anything that involves player interaction (that's more complex than clicking anywhere on the screen, that is). The absence of any minigame was quite disappointing. I ended up playing... close to nothing. Only a single choice at the very end - said choice doesn't even lead to a different background picture, merely different dialogue text for 5 to 10 messages and that's it.
It seems like your studio is focused exclusively on VN's and is going to produce as many VN's as possible in the shortest amount of time. Please... If you respect yourselves, if you respect your audience, us, please for the love of God, don't do that. Please don't spam the game portal with re-texturing of the exact same concept over and over and over again. Please, explore some other genres, bring some fresh air! You have nice artists in your team, put their talent to good use! But please, don't give us a mere edit of the game we previously played. If you want visibility, originality will pay out much more than flooding the game portal with as many games as possible.
REVIEW OF THE STORY
----------------------------------
You seem to urge your reviewers that your games are visual novels and that it's normal that the only interest of the game is the story; well, let's review the story then!
Suicide is always a sensitive topis to talk about, and making a good, "feelable" (as in, we can identify to the protagonist(s)) story on that topic without being controversial is rather difficult. In this case, the story is quite cliché and easily foreseeable. Since the story is very short, we don't have enough time to identify as the protagonist, so instead of making a "feelable" story, you chose to make a story with a morality. And that's okay! However, the morality isn't original and bring nearly no new thought on the topic.
That's quite a weak story; that has a significant impact in a game genre where the story is super important, and that's even more important if you choose to discard any other game element.
I see you are getting many complaints that your games are empty of gameplay, and you argue back that this is a point of a visual novel. While I could argue that most (good) visual novels always incorporate something to get the player involved in the story (often in the form story branching - preferably complex enough to not be foreseeable - or in the form of minigames, sometimes both), even if I choose to respect your decision and accept that the entirety of the game is only a linear story, the story itself isn't interesting enough to keep the player hooked to the game long enough.
The story, only interesting point in the game, isn't itself enough to sustain enough interest from the player.
MY SUGGESTIONS
---------------------------
If possible, switch game genre, at least temporarily. Visual novels aren't exactly working now; this would be fine if it was your first attempt at the genre, but this is your 6th attempt, with little to no improvement whatsoever over time. Why not make a point-and-click instead? I can easily see a good point-and-click game coming from your studio with your current skills. The genre switch could help bringing some originality in the gameflow.
If you really need to keep doing VNs, switch plans for the stories. Instead of remaking a new dull story every time, try making sequels. I kinda liked your idea for "No Help No Hope", but I found it quite short and rather basic; why not making a sequel? It would justify using the same game engine and at style, and if would show more of a story that's currently underexploited. You can even make a single, big VN, and release it chapter by chapter; it would let you keep doing frequent small releases without making it look like a flood of remasters of the same game, and it would allow you to create stories that are a bit more complex and interesting to get into.
I wish to see some new, fresh, original content coming from you. If you attempt something new, I can offer my help (programming, testing, proof-reading, anything). If not, then I wish the best of luck and most of all, the best of inspiration.
