Yea, not my favorite. But NTR is used as a blanket term for all types, and the game is 100% Netorase. So still holding true to the name, lol. I think, as a few others have said, the biggest flaw with his last few games, is having many routes. When the girl is getting nailed by 5 different dudes, it just cant establish a proper Netorare feeling for me.
Somthing like Seson of Loss works so well because he spends a long time building up the NTR with one guy. If your gonna have multiple guys, it needs to be something like Scar of Summer where they are completely separate routes, not on the same timeline.
