I Wanna Be The Guy - Complete Run (Part 5 of 5) /w ending

This is my video of a full (complete) run (all secret items and bosses) of IWBTG (I Wanna Be The Guy). It's devided in 5 parts, so that I could upload 'em all to youtube.
I , sometimes tried to go thru the screens as fast as possible (sort of speedrun or rush it) (also tried some boss rushes) and I made the video so that it would be one continious movement. (no screen skipping/dieing/saving and no pressing s at boss fights).
I also tried not to use any bugs and to play so that people would know where the traps are etc. (Sort of a walkthough)
Although sometimes you couldn't show everything, because that would get you killed and I didn't want that ;).
I did all this in hard mode, but sometimes busted my nuts because I didn't wanted to save at some points to make it look smoother. When I was reaching the end I realised I might as well had tried it in Very Hard mode, but that would probably have costed me a lot more time and since most (sane) people don't even try to go there I thought it would be better just to show it in Hard mode. (I have not tried to play in Very Hard mode and to be honoust I am not planning on doing so :P)
There is a small section of the vid that goes a little bit out of sync.
When I was recording it it actually went off sync big time, but I manged to tone down it a bit. But you do notice that the recording isn't acting normal. Also the vid quality goes down a bit. This starts in the 'Final Tower of The Guy' and ends when entering the Room where you battle The Guy. (So it's the part where you need to go up as fast as possible). Don't know why it goes off sync everytime there, but I tried to fix it as good as possible. The rest of the video is 'normal'. :)
Here's part 5, enjoy.
