timer time

Oh my!
I spent a lot of time trying to fix that timers!
You know, when you press 'i' once, but game opens and close inventory dozen of times, until you release the key.
Yeah, yeah. Easy job, but for some reason, it wasn't 'that' easy and eat up a lot of time!

By the way, about timers.
I used none to prevent flipping effect, even I was speaking of them about a month.
That's the story, the solution was so simple.
You should think out of the box.

What do we have left?
Menu, music and few fixes.
