Hey, nice to see the game is coming along. Here is some of my feedback. I'm not sure if making a topic, or replying here is the best option.
The way I see it right now, the game is going to need to figure out how disconnected the dating/sex is from the delivery system in it's current and future state.
The teleport system is overall a good idea for those with 0 interest in the loop. But it carries it's own problem of making the system feel even more pointless for those who actually want to do deliveries.
When it was set in a small town, it made sense that the sole delivery guy would be able to build these kind of relationships with people, but the change to a large city not only makes the deliveries harder to complete, it also makes the big empty world feel even more shallow, with the MC somehow delivering the exact same orders to the exact same people.
I don't have much advice on how a 100% "everything is tied to delivery work" thing would work, because just going with the classic "delivery guy" porn trope is just gonna result in all the characters feeling the exact same after enough deliveries have been done. I can definitely understand the more outgoing personalities being eager to flirt and get to know the MC better, but not every character is supposed to be like that. It feels like there has to be some other way to romance the others outside of this loop that feels more natural.
Even so, I think being able to do deliveries to non-modeled, generic NPCs that exist solely as delivery fodder would help the world feel a bit less empty, and fits the big city atmosphere the game seems to be going with now. If you've seen those Youtube channels where people film their Uber Eats shift, you'll know what I mean.
This is a very light worldbuilding complaint, but it's a bit strange seeing how the MCs human status, which IIRC is supposed to be the same as seeing a dragon flying IRL, is no longer at all referenced in the game in it's current state. You can even freely take your mask off and no one seems to mind, nor do any of the characters bring it up, even during sex.
I'm not sure if this detail has been softly retconned, and now humans just exist alongside the characters, whether this is something that'll matter further into development, or it's simply been forgotten.
Again, this is one of those details where you need to think how the different personalities will react to the information once they get it. I don't have much advice on this, other than perhaps some type of "suspicion meter" that fills when the MC fumbles a question about his species status, or is seen without his mask. Then again, sex alone would probably cause this to fill up, unless the MC convinces them he has some kind of shaving fetish, or never takes his clothes off.
I hope this feedback doesn't come off overtly harsh or mean-spirited, I truly do appreciate what you're doing with the game, and I think some people didn't like the shift from a small town to a big city, but I personally think the idea itself is fine, but it definitely needs some work down to make the change worth it.
