Not possible atm.
One of the features that is definitely needed, is to at least adjust the text speed and transitions. It is just horrible, that a line like "zzz...zzzz" that needs no time to read takes several seconds to advance. Even better would be the ability to simply skip text or roll back, like in RenPy games. Another feature, that is better in RenPy is the save system. Simply being able to right click and save/load a game is great for the user or clicking the middle mouse button to hide text boxes. I think a lot of people will complain about that, since the story format of this game is just so similar to other RenPy VN's and everyone is used to that. Ease of use and functionalities like these for the players should be a high priority when making games in my opinion. So if you start to make a game like this in any other engine than RenPy, there needs to be a good reason for it. Taking away these kinds of things just make it feel comparably worse and will attract less of an audience.
However, that are just my two cents so take it as you will, but i think a lot of the comments so far are of the same opinion.
All of that aside, the renders look good and the story could be good as well, from what i've seen so far.
And on a last note. Is the TV screen, when the player wakes up and talks about watching to much porn, in the very beginning supposed to be just a white sceen with (i think) your name in the bottom right corner of the TV screen? With this context it looks like it is supposed to show some sex/porn scene but it is simply blank. Maybe the picture is missing? Same for the sex scene with Mia, just before the end there is a white screen. It sounds like she is giving the player a blowjob.
