Syobon Action is basically a remake of Nintendo's cult classic, but with a little 'creative license' added for kicks. Every platform you stand on could be a death trap in disguise, and collectibles are often booby-trapped if not made extra difficult to acquire. There is also a nod to The Big Adventure of Owata's Life towards the end.

Music is from Cheetahmen II (Super Ghouls and Ghosts for level 4). Videos from stage 2, 3 and 4 are in the extended. Unforgiving! [source: Lord Jezo]

From the comments: The video title says, roughly, 'A Mario-like game I wrote myself and then made my superior (co-worker) try to play.' Text shown with the blue screen is 'omake', which basically means outtakes or bonus footages.
