Just finished v.0.15 right in time for v.0.16.
FEEDBACK:
* A few of the sex scenes are "looped" with continuation being determined by user input (<Enter>/left-click). That's a nice touch as it enables the player to control the speed at which the scene progresses. (You can drag it out, or you can zip through it quickly.)
* The new Achievement interface is also nice. The player can see at a glance whether or not a character has been "completed" for the current version, and revisiting a scene is easy to do.
* The "Not yet..." and "Under Construction" error messages are a relief as they let the player know when a path which is temporarily "closed" should be revisited. (e.g. There is a small error in the v.0.15 walkthrough with the timing on visiting Sophia's house, but the game guides the player to try again, later.)
Overall, the game feels "high quality," well-integrated, and full of "quality of life" touches that make navigation and gameplay much less of a chore than in some other Renpy games. I'm also interested to see where the story goes from here.
