Has anybody ever played the hardest game of all time...'I Wanna Be the Guy'?

[Danger Mouse]

After seeing countless videos on You Tube dedicated to this brutal game designed by Satan himself, I had to download it and try it for myself (it's an indie game and totally free).
I managed to make it past the first boss, but it is every bit as brutal as they say.
This game hates you and enjoys your pain.
Here is an example of how unkind this game is:

So has anybody else suffered at this game's hands?
If you like a (ridiculous) challenge that's really addicting and a tribute to old school games, then this one's for you.
