Thank you for playing! I'm glad you enjoyed it. Development has been slow the past few months due to some health issues amongst others but there should be a new version of the game out soon!
There will most definitely be watersports in the game, as its one of my big kinks as well. However, to make sure I don't scare off the audience that may not enjoy it, watersports and one or two other kinks will need to be enabled via an in-game toggle. Still debating where to put that toggle but it'll be somewhere.
Asuka may very well be the one that teaches Natsuru the pleasures of watersports or maybe Natsuru will stumble upon it herself? The possibilities are endless, so look forward to it! :D
Yup, there's a lot of tweaks that need fixing with the game. Hopefully by the time the next version comes out, most of those will be fixed. Stay tuned for more!
