he reworked the game (added hints,phone, new text box and interface, also a different way in the dialogues with heart bar included) while making that 0.1 a prologue, what you seem to recall may be the last update of the 0.1 game.
The xmas content is still in a dream sequence in the 0.2 so u dont need it.
the 0.2 start after the events in 0.1 so u dont really miss anything if u have already played them, u can even recall 1 sex scenes of 0.1 in the hospital (though u cant recall those other sexy scenes of 0.1 with mom.sis etc, only the girl in the hospital xD)
@Baxonius you already have the phone for that, just read the messages the girls text you, that hint enough what you have to do, also remember to check the backpack and shop for ítems. (after you get the ítem use them like the lockpicking in the door of Mom or the maid dress on the cafee shop girl)
