Thank you very much for your message!
This is the first version of the game and I didn't want to put all the features in it to be able to release it earlier. So in the next update, a lot of things will change.
For the controls, I don't think I can make them custom yet but changing them is possible.
For the girls mechanics, I was planning to put in place several game modes including the story mode. The mode you have access to is the sandbox mode. That's why there is no progression in the game yet.
