The dev took a pretty good and well tested idea and released a really lazy version of it. In order for NTR relationships to progress you need to either run out of stamina on purpose or leave the girl behind and rest at a campfire (no benefit to this since they're fast travel points and sleeping doesn't restore stamina). You then ALSO have to choose which guy makes a move on her, or if nothing happens. It ends up being a really boring standard CG collection type game with some extra busywork. The art is well done at least.
All and all just a disapointing waste of potential.
