Overall a good game! For a simple explanation, I'll say it has great scenes but a decent amount of grind. Also, for reference, I have only watched around 30 One Piece episodes and have no connection to the IP behind this game. As for the more in-depth explanation:
The Good: The scenes are very well done. All animated, even simple teasing/early training scenes. The animations are great and above most of what I see on F95. The characters are distinct enough from each other, although they don't have deep storylines other than their basic character traits. However, I'm okay with this because it's better than overexplaining every part of their story. Too many games have so much exposition and info dump every character throughout their storyline without a fair trade in the amount of content. Worldbuilding and character depth is important at a point, but for most porn games in development for less than a couple years, I would bypass those for content anytime.
The Bad: It's a trainer game, so prepare for some grind. Once I found out it was a trainer, I expected a decent amount. The scenes were very much reminiscent of Akabur's training scheme, with each type of training having a few hearts and maybe a choice per scene. However, there was some extra grind that I wasn't too fond of, including the strength training, jailbreak stopping, etc. Not that I don't want to do events like that to build stats, I actually enjoy that mechanic. My main issue is I had no idea what milestones of these skills would earn me new scenes. So I had to kind of spam scenes until I got a new one or spam training until I got to a ridiculously high level. For strength, it tells you at 30 that it's not worth training. For the other skills, I never got to a level that told me that. That's my main gripe with this game.
Overall, very excited for the future of this game. The developer seems competent and the product so far is very worth playing. Highly recommend to anyone who enjoys the trainer genre!
Note: Review was for version 0.1.2.3
