wat
First attempt for me was less than 2 hours (first attempt = sight-seeing all corners in the maps)
What took you so long?
My first attempt took me at least 4 hours and some walkthrough visits

Especially in the escape part, back when I was too pussy to get the guts for a slap or two in the face because of the challenge.
Plus, sometimes I just abuse of the game's technology (especially the momentum) to speed-run through the game, so I don't have to do some of the puzzles. (which usually results in failure, but sometimes I can do it) :razz:
But yeah, this Thursday I have no school, so I'll try to complete this damned game in 2 hours non-stop. (HOPEFULLY)
