Why don't you jsut let doug go to town on one or two barrels? He'd quickly find himsel having more alcohol than blood in his system, which I'm pretty sure would be fatal.
It actually is a subtractive color system. For instance, combine cyan and yellow in the sandbox and you will see them turn into green. http://en.wikipedia.org/wiki/Subtractive_color
Years of magical sutdy, and we never learned a spell to carry more than two orbs at once, or at least levitate the others behind us. Good game by he way, more challenging that the puzzle style suggested it would be.
Also, there are (technically) 5 endings, love, perfect love, money, perfect money, and compromise. The only difference between the perfect ones and their non-perfect versions is the lack of memories hovering above the pictures in each one, they can still be used to get the auxillary achievements.
There was one idiot who I panicked while they were in the basement, the went up the ladder, ran up a flight of stairs, and jumped out the window. They took a longer route to kill themselves than it would heve been to run away.
