Echoes of Lust (S3E3) was a good game that slowly got worse. Specially towards the end of the second season, it just lost all interest to me. The base is a classical "sandbox" where you have to do different tasks to advance each girls' plotlines, but with no farming. Thing is, since it's a time-loop, it does make sense that every girl keeps the same routine, afterall it's the same day. Unfortunately, the story loses some points because the MC actually doesn't care much about the main plot and why the time loop happens, and only thinks about fucking, which is a pity. Girls were reasonably interesting and their stories evolve within reason, even if it was too cliche in how that was done. As the story advances, they quickly start losing interest and depth, instead of gaining them.
Renders have a high quality. Not as much in the animations, specially in the earlier chapters, though these increase in quality as the game develops. Sound is awesome, with all girls voice acted (in the first season only so far, I guess second one will have it at a point) even though, since it's done by only two girls, their voices sound a bit similair. Sound effects are nice and music does it's job. And, as far as I've played, haven't found any bugs and I'm almost through the whole game (what's available so far).
So it was originally worth your time but, as it stands now, I've ended up dropping it. Not worth it anymore.
