You cant at current version.
I think saddog spent too much time on teaser/preview pics, not enough time on implementing them in the actual game.
The 4pm event is the sneaking into the basement with younger sister via the option in the mcs room.
Their is a lot of harsh bullshit being thrown about at the moment, what is wrong with you people?, you are getting the game for free, you are getting the extra images for free and yet for many of you it is not good enough, and yet each of you want a slightly different thing so unless he is writing an entire other game for each person with an opinion on this forum, you aint ever gonna be happy.
The game is developing, yes the word is developing and wherever he intends to take it thats where we end up eventually whether you whine about it or not.
This update is not a biggie but it has a lot of subtle improvements, we have follow on conversations and scenes and a full new 3 option bathroom scene as well.
I have played through all of the changes (I think?) apart from the make out scene with little sister, so their is quite a lot of differences from the last one.
I appreciate that many of you are equally supportive of the game though so this is not aimed at them.
And after that rant if anyone knows how to play through or active the make out scene with sister, i would appreciate the low down.
