Thanks a lot for the detailed feedback Maty. I think I agree with you that the intro is a little too long now, and the way it goes deeper into the themes is more rewarding for returning players rather than new ones that want to get to the point and see what the fuss is about. "It takes a while to get going" is something we see a lot in post 0.2.5 feedback.
Considering that there's a persistent variable now that tracks whether this is the player's first playthrough or not (for now all this affects is the poem read at the start of the game and makes the popup letting you know about the SFW mode appear only on your first playthrough), speeding up the intro for first players and keeping the extended one for returning players is A) not hard to pull off and B) potentially very interesting. I don't think it's a super high priority (we're busy enough with 0.5 at the moment), but still, I'll definitely bring it up with the rest of the dev team at some point.
Thank you for pointing out the rest of the issues like the missing background and lack of polish here and there. I'll get those fixed for the next version.
