I tried Demons of Harem and I liked it, despite the character models not being top-notch like here, it managed to win me over due to the fact that I didn't play with Issei as the protagonist. Although his dragon powers are top notch, his personality is deplorable.
And about the "walking Sex Simulation of Demons of Harem and sex with a stranger", I didn't see anything wrong either, of course there was a lack of a good story there, if Dev knew how to explore it. Maybe it's his first game, who knows, but it wasn't a totally text-loaded game, I've played games like that that promised to be erotic VNs, but in 3 hours of play I didn't see a perverted scene. I like it when Dev adds a perverted scene every 30 minutes of the story. Like here, I just played Devil's Academy DxD and found it acceptable. after all, Dev knew how to balance the story and perverted scenes.
And what really killed me here was the boring "sacred flames" and chess minigames that you need to do to be able to follow the next chapter. positive point, I can change Issei's name to mine and show a different character as I would like to be, the choice options in the answers help me make Issei less Simp.
Anyway, I would even recommend Gremory Live [Ch.4] [Kamos] to you, however, he is a Dev who develops his games through the patron community pool, and most of the time when he does a poll it is always the same game "Sarada Training " who wins the poll, even though the game's plot has ended, the other games are left behind.
