Boring. Theoretically functional.
Criminal (heh heh) lack of lewd compared to the time spent.
I was kind of hoping for any kind of gameplay from the description of "Trainer" and was disappointed.
You have an option of doing 4 actions per day, which are chibi-characters doing a 2-frame animation. It raises one of three stats.
You grind that to unlock a scene, one per three different milestones reaching the desired levels.
Or you don't do that and waste time to grind money so you can grind training so you can grind three different levels on three different girls, which all degrade when you're not interacting with them.
Occasionally there will be an end-of-day event which can have bad events, and is goverened by a %chance on the good/bad spectrum. Save manually daily. Autosave will screw you over.
Just a lot of busy work for little reward.
Also your MC is an absolute idiot in ways only hentai protagonists can be.
He finds a dildo, thinks it's a drug dispenser, and licks it to try and taste the CBD oil.
That is his first action. And he gets dumber from there.
I'm sure this is someone's cup of tea, but it sure isn't mine.
Art's alright, at least. Hope you tig ol' bitties.
