For the time being (I just played the first 'arc', as in getting lvl5 and hunting down a certain coward), it's pretty neat indeed, apart from some oddities in the animated H. I'm afraid though that the variety of content+variety is not up to par with its length nor making it a really satisfying game long term.
15 'big' H Anime Scenes and about as much repetitive small ones border indeed on being too few. 12-13 Base CG plus Poses tend to be the 980 Yen works... or what should be 980 Yen. Big works go for 40+ Base HCG.
The combat which sure reminds me of Slay the Spire I like but it is short of being as addicting and is actually in danger of becoming close to 'I just want less consuming standard RPG maker combat instead'.
It's a sad matter of fact that it takes longer and is by far less rewarding. By balancing the game around being basically ungrindable, all that is left winning is a little bit of money and material. While there is choice in building your deck and character, it's limited.
I really recommend the group to vastly extend either the H or the gameplay lest their games will become stale quickly. Of course, both would be perfect but welp... finite resources and all that.
