I find the story beats interesting, but I can see why other people would complain "nothing happened" -- it is not that nothing happened, but rather, many plot points are sprinkled like hints through word of mouth of several characters, and not emphasized. Details like how...
...may seem obviously important clues and details for players who really pay attention, but it otherwise just feels like flavour text.
My advice would be highlight text words which you
want players to pay attention to. For example: different demon names get different colors, so try to make it so any word or sentence which signifies plot points related to certain demons are colored just like the demon names.
Back to the story, I find it incredibly funny that--
--which is honestly entertaining, but might seem a bit hard to believe. Are individual demons quite limited in their range of abilities here? Or did Gloria simply not want to dirty her hands and would rather have Lust do so? Questions, questions~
The plot thickens, and just the beginning of it. Now we start to get why Lust is here and like this, but not
how. Eri's mom is probably the next step to unravel.
You did good work. Just like before, I will offer more suggestions.
First time, I brought up using hypnosis techniques, which aren't supernatural and thus don't leave traces for others to pick up. This should be a good time for Lust to start considering to use it, since Gloria found him through these traces -- Lust isn't stupid, he should know if Gloria can, then people who sealed him or exorcists can, too.
Next, I brought up the idea of Lust going on dates with any of the girls so he can learn more about the modern world. This is mainly for romance, so now it might not be feasible yet, but I am sure you have plans already.
I also recommended using image club-type prostitution house, which is rather unique to Japan as it involves girls in costumes as well as simulating perverted/kinky real-life situations to satisfy customers. This is not that important, mainly just me recommending a place for you to try various character designs.
So this time around, I will recommend a quest system related to Gloria.
Given she has a large company and Gloria herself mentions giving another woman for Lust to drain from, it should be fairly interesting to have an assortment of quests related to the company and assisting Gloria, each quest unlocking another female to have fun with. They don't need to be plot relevant, just additional options~
What kind of quests it could be depends on Gloria's company, but a relatively simple example should be to accompany Gloria or other workers for business negotiation. Lust also seems to be handsome, so his face should be good for advertisement making, or for fundraising activities.
That would be all for now. Keep up the good work!
