It happens, I like your more streamlined multi person games, Vanilla games tend to be boring without an interesting concept behind them, this one also had no build up, it would of been better if it was more inline with the actual universe and we saw how kazuma got so good with the ladies... maybe like an incubus spell or something. I think this would of also been better as a larger project and an adventure like a less grindy version of chara dungeon, there is a 3d version of that with some ntr themes and it seems well liked(I didn't look at their patreon numbers). I do also think konosuba is overdone as a solitary source of content, a site I know you frequent has numerous konasuba games. Most likely due to konosubas popularity. For what it's worth the hentai scenes in this were great, the descriptions were a solid step up and the multi person scenes were a lot better then your other games. Hopefully you can put some of that into your next game.
