How many characters have fleshed out dating? I've only been able to get the one scene with Garreth.
Currently, Garreth has 2 free time segments implemented, Kovle has 3, Brymror has 3 and Cedrik has 1. The only (proper) sex scenes currently in the game are those during both of Garreth's dating segments (second one not having illustrations just yet, although we have commissioned them from Lumix already), and a secret bad ending that you can access if you are really into Mindalu and let yourself get captured by her during day 4 after persuading her not to fight you.
We are absolutely going to add more dating content over the coming year as well as advancing the game's story. We expect each character to have at least one sex scene after a good bit of character development and romance, though this number may vary per character. The game's content currently is roughly about 20% written out, so yeah plenty more to go.
