I really don't see such big problems with stages being shorter, plus they could be divided by content.
Like certain lines/trains will have only toy molesters, only molesters who does hypnosis and other mindfuckery, common molesters that use hands, train that is full of hooligans which will attempt to tear your clothes or restrain you, or mix of this or that.
With that there is also a good thing for end game content. Like your own train, where you can choose what type of enemies you want to fight. (Which this game 5th-line really lacking)
About game skills, perhaps we will no longer have this rouge-like stuff but will just gain exp and unlock skills and will start with what we picked or learned.
I dunno, since its just a planning stage it's in a completely free state and can literally be anything.
Dev can turn it into RPG, Shooter, make it similar to first one, or completely different.
Plus new and new idea will come into his ears. (Want he it or not)
My idea would be to make Some kind of Shop where you can buy stuff like items and clothes (spare underwear in case it got stolen, or pantyhose/stockings for this type of kink), bookstore where you can buy skills both good and lewd, some kind of spa/onsen where you can relax and remove debuffs, hospital where you could check your pregnancy if there will be such thing, home where you can recover your energy or hotels where you can do the same but for money which you get for each caught molester or something else. And In order to reach this or that location you need to travel via trains.
Or maybe some kind of fame.
If you arrest molesters one after another, it goes positive and weak molesters will attempt to avoid you, but more dangerous one will take interest in you instead.
Or if you will get fucked left and right, it will go negative and more and more weak ones will come for easy prey, taking you with quantity to point when even regulars would try this slippery road just to touch you.
- but I really dunno how actually dev will be interested in implementing such shit ton of stuff or how well will it work with his plans.
Because it pretty easy just to yap and give "good ideas", but the one who does the most difficult part, who will making these ideas into the game, will be him.
And now, I really hope that he wont get overwhelmed or too stressed, due to all of that attention, new game expectations and stuff. Burnout could happen because of that.
About animations, I already said my thoughts.
I'm preparing for worst case scenario which is: animations will no longer be in game, instead it will be like in most RPG games.
- But if it actually only Game Over scenes and game stuff will still get animations, that will be great.
Because after such detailed animations of groping breast, nipple teasing, fingering and all stuff with toys, simple pictures that just fade in will be quite a downgrade.
