This one makes it look rather easy but knowing the Bit Trip. games I'm sure that the difficulty will ramp up quite a bit.  IGN has some more videos up that you can check out by pressing the embedded player. 
 
Out of all the Bit Trip game up to now this one looks like the most colourful and detailed. The Bit Trip games have always been inspired by video games and it looks like this one is no different with the Mega Man nod with Commander Video's slide move.
I'm quite curious what kind of world Commander Video will find himself in in the 5th game in the series after this one since he has been evolving quite a bit throughout the story (which I'm still not all that sure about what it is about ^^)
