Fantastic work so far by the developer. I see a lot of comments lamenting the incomplete character paths, but in all fairness this game is still in development so incomplete content is to be fully expected. For what it's worth, there is already a really solid amount of gameplay and content here, and if you've been on the fence about this one but you enjoy trainer/dating sim games, you may want to give this one a shot or at the very least keep your eye on this title.
I can't speak for the previous versions, but this is definitely worth checking out now.
Quality stuff,
ParadiceZone. Keep up the great work! Your animations are really, really well done. I think the grind could perhaps use a bit more balance, for example the swim training seems to be a bit repetitive but the teacher interactions seem a little too quick/easy to progress. It's a tough balance to strike though; you want there to be enough grind that the player feels they have to work for the lewds (because it feels more satisfying and rewarding when you have to
earn the lewds!) but not so much grind that they get bored.
Maybe you could incorporate alternative filler text that changes depending on the current relationship between that character and the player...that's just a random thought though. Ultimately I think the best approach would be to find some way to make the grind more interesting either through flavor text or additional filler CG's/animations. Perhaps even something as simple as visible stat progression would help to balance things out. Not sure though, just throwing some ideas out there.
Personally, I'm not sure what the best way to approach this would be, but I think you'll get there and you're already well on your way. Best of luck to you!
