If it actually had the combat in it.. It could be fun but just skip options and grind power for no reason as you don't have any battles make it really boring and uninteresting. Dev needs to pause on story and work on combat this is suppose to be episode 5 but it's just grind away for nothing.
I'm aware that I am making a hentai game, as such my main priority is to reach the point where MC can lewd Rias and Asia as those two will be the first two relationships. I wouldn't really feel at ease focusing on combat and other things while the game lacks what the majority of people would find the most interesting.
The game is currently using a few placeholders and there are many missing features as well outside of combat, including pieces of content (R6 was meant to end with you "spawning" back to your room so you can interact with Asia, etc.).
The reason why you can "grind" (although there'll be no grinding in future as by skipping combat you'll be receiving the same experience for winning) is because my game's save files will always be compatible, so in a way, current players have the advantage of quickly reaching the episode where MC and Rias/Asia finally start having a relationship.
For those interested in combat (and the currently missing features/content) they can always start the game over at that point.
-edit-
Also forgot to mention that some of the important choices will require stats, an example is Raynare's, but there'll be more. So raising up your stats is useful even without combat.
All I wanted from a dxd porn parody game was a custom story with mc stealing the girls from under Issei nose and yet out of only 2 dxd parodies they both are doing same thing, canon Issei mc story + porn and even if there are differences at the core the story is going to be the same or extremaly similar if both games want to stay true to the canon also they both use koikatsu too. A shame dxd is so niche that no more games are made but then again if the 3rd one would also be canon Issei mc + porn maybe its for the best.
I am against all forms of NTR, so at the very least I won't be the one doing that
However, I'm not fully dependent on Koikatsu, I use it more as a helper. There are things Koikatsu cannot do, such as a lore-accurate Viser:
Which is also not the same as the Anime one. Even the Issei at the intro of the game is not made in KK, but traced. Same goes for the first NSFW CG at the intro, although that's very Koikatsu looking as it was a very old attempt at tracing (You can see the outline, but when it came to recoloring, I very much sticked with KK style).
Unless you're specifically looking for NTR, the MC of this game is not the same as the protagonist of the anime. This is due to the fact that I am not able to replicate it 1:1 since this is a fan game, and also because the protagonist of the source material is designed to avoid sex scenes, while in my game it's the exact opposite.
ideally a small ecchi scene, but a plug in with "good boy Issei" would do too. Its easy to impliment and it really boosts the powerfantasy feel for the grind lovers.
Good idea, I like it! Noting it down. I am not sure if I'll specifically use it on that minigame, but it's a good one.
The sandbag minigame is actually meant to be short, not a grind. However, at that point of the game you're missing out on about 1000 experience due to the fact the battles are missing, including the experience when you're skipping them. So you have to play that minigame to gain that 1000 experience as well.
Although, your idea gave me another one: In future I could add milestones (Scores to reach) for every minigame which unlock an ecchi scene.
Maybe an achievement list similar to Legacy of Hestia, but rather than unlocking side stories, you unlock ecchi scene rewards
Anyway, love your suggestion and will definitely implement it in future! If you got more, let me know (Including any scene you'd like to see in particular).
