Since no one seems to be able to play past a certain point, no clue. I don't see any 'swinging' in the game thus far.
See first answer.
Swinging is when the MC swaps girls with another man; the MC sleeps with the other man's girlfriend, and the other man sleeps with the MC's girlfriend. This is just a couple swap. (A swinging couple may practice other types of fetishes, such as cuckolding and bull roles, BDSM, open marriage, among others. Not all swingers participate in other fetishes and share their girl with a single man.) Netorase is when the MC lets his girl have sex with other men and enjoys it. (This doesn't preclude having other fetishes like humiliation, SPH, sadomasochism, femdom.)
Small compared to what? Does he have a 3-foot penis? No. Looks average for porn games, which is pretty big. There's always someone with a bigger one in these games though.
We're talking about a game, and logically, it's not about comparing it within the game world to other sexually active men. If the MC has a penis that reaches his knee, but all the other men have penises that drag on the ground, then the MC has a small penis. It might seem silly, but it speaks to the focus of the game, the way the MC is built. If the MC is built for NTR , he has a smaller penis; if it's for romance/harem, if it's average for the game with small variations of 1 to 3 cm, he's trying to balance the content. And the excuse that the MC is average 12 cm according to the International Association of Urology doesn't convince anyone anymore.
It's a one person project (I think) so slow development is justified IMO. Looked at the code and it isn't simple. Looks like three branches with various paths. Not easy to code. I'm doing a much simpler game and I'm lucky to get one chapter done a month. Heck, some animations take a day on a 4080S. I say, give him a break.
First, I'm not talking about release schedules, whether it's monthly or semi-annually, that doesn't bother me. I play some games where the developer releases annually, and it never bothers me.
What bothers me is when it clearly starts to disregard the path I'm playing, failing to create adequate content. This includes scene transitions, conversations, environments, and character behavior. It's not enough to just cut out the netorare content and change one or two lines of dialogue like most games do, since the rest of the content is screaming NTR at the player.
No developer is obligated to create other routes, but if they intend to, they should do it well, unlike most games that aim to blend romance/harem and netorase/netorare/sharing paths... It's not enough to be honest, it has to seem honest. This is where many developers fail; in the scene where a guy approaches a girl, the behavior and dynamics of the scene will be different. There's no point in creating a scene for romance/harem and changing two lines to make it NTR.
The questions are designed to determine the main path; everyone has their own tastes and favorite fetishes, and this always becomes visible throughout the game, evident in the details and whimsy that each path takes.
There are phrases that are quite cliché when we know that the romage/harem route will be relegated to the background:
The romance/harem route is realistic.
The romance/harem path is a slow burn.
The MC is like that so the player can identify with him.
The MC is no longer realistic, which is why the sex scenes are like that.
The MC isn't the guy with the magic penis.
It would be easier for everyone if the developers were honest about their preferences and focus in the game, what their fetish and intended content are, and the forum tags don't help either.
I've never actually programmed a game in Ren'Py; my area of expertise is legacy financial systems and banking systems.
