Ok, simply put, you want to get people to have as much satisfaction as possible, and annoy them as little as possible while they are playing.
On satisfaction front:
1)Dont blow up slave village via Android 21 shenanigans. Keep it. Use it. Milk it like no tomorrow as a main side activity for the actual plot.
Waifu collectors like mobile fate/grand order are a billion dollar hits for a reason. Fill said village with secondary dragon ball characters you may capture along the way. Bratty girls like Videl, Bandits/space pirates like Launch and Zangia, some demon girls like Towa. And potentially, maybe even add some progression with sex scenes to those secondary characters that people like the most, upgraiding them to main waifus at the end.
2)Add some more actually empovering, and preferably lewd options when dealing with mortals. For example, Vegita starts shit with Tuffles again, or gets brave enough to demand his former wife back, and you have options to symply beat him up, beat him up and fuck Bulma right in front of him, or just kill him.
Is it stupid long tearm since it either leaves you with mortal enemy, or drops your universe power level?
Maybe, but putting down self-important characters like him, Cell or Freeza from time to time - is one hell of a power trip. And thats what we here for. To feel like fucking gods.
Don't just give us stuff like choices on killing or sparing some kid. At the very least add pleading mother or older sister to the scene, with one of the options being you sparing the kid if she spreads her legs for you, and maybe another sub option being honoring, or not honoring the deal, and maybe even deciding to keep the fucked girl as your slave regardless of previous choices.
3)More jucy descriptions of sex scenes in general, as well as plot hooks that lead to them and actually make you want to stick around.
Character ambitions like - "impress Zeno", for example, are simply not interesting. They don't promise you potential rewards, potential smut, potential power trips.
Now, for example, getting one of your universes mass raided by that new 13th universe as a start of the arc, gathering(with varying degree of success) all the important waifus together under you, on the basis that they can be captured outside of security of your planet otherwise, and then start some millitary to raid the resurected fuckers back, potentially even conquering their dimension, with all the benefits of conquest that come along the way(kill the baddies, resque some of your girls, capture and enslave the enemy women), that's a plot hook worth sticking around for.
It promises action, it promises smut, and it promises power trips. All the thing people usually expect when it comes to NSFW fanfiction and games based around dragon ball universe.
Now, as for how to make your game less tedious:
1)As i said before, god with one point of stamina is no fun. Especially as of now when you also have to go trough the same coridor towards bed, and listen to some additional repetative bullshit along the way. A clock shaped button under the "local map" that would allow you to skip going to bed trough multiple steps, or some early game mechanic that increases hero's stamina so that he could do more than one action before needing sleep - is a must.
2)Finally having "map" of your personal planet is a nice start. But my point about having interactive list of characters you can visit in your castle, instead of image with six unmarked doors, stands. Its relatively easy to make and you can have more than 6 girls to select from at once.
3)Dont make options that are unavailable for now - visible. The said planet map, as well as galaxy maps, have tonns of places that you cant visit, and frankly, not only it makes the game feel far more unfinished than it is now, but it also breaks the whole "I'm a fucking GOD" feel really fast. You don't want that. Make them visible only when story allow for their usage.
Hope this helped a little.
