Ok, after finish all 3 routes I can give a shot about every:
1. Love route. Good written, but feels like some lack of content. Much focused on MC, his GF and (if you play along) - other females. Good shit, potentially can grow into Harem if Dev be loyal. Will see about that
2. NTS route. Not a fan about this stuff, but in this game it surprisingly good written, a lot of content with a lot of characters (renders and videos), huge respect for possibility to chose almost all events to start or skip with GF and other girls with other mans (some events can be avoidable even in mid action, insane).
Currently - best route with maximum output with you choices
3. NTR route. Dont even try this peice of shit. Is it so bad written you dont even emagine. Fuck, destractions by games? Stomach ache? Seriously, Dev? That most stupid twists i even seen in ntr games. Facepalming every time that this shit happend. All that route need to completely rewrite, for now - absolutely unlogical and stupid piece of code...
