How could a game be exhausting when the puzzles are solvable?

I have not finished the game(yet?). I went as far as the school gym...
But having all these pieces of stories with no real solid link is overwhelming to keep in mind. The only attractive thing is the writing style...
There would be only two or three storylines, it would be nice, and maybe there is only three, who knows? THIS is the problem. (I must say I play with gargoyle, so I don't have the colored interface.)
Giving the fact that playing itself is not really fun I think I will give up.
But something wants me to continue, something wants me to see all the pieces come together at the end...
It is like suffering a long run to get a promised ice cream... but I am beginning to wonder about the taste of the ice cream.
