An admirable attempt, but...
For both the Madness series and the T E T R I S ' D video you are "parodying", this does not match the tempo at all. The music especially.
Also, if you are making a parody of T E T R I S ' D...what element of it are you making fun of? Yes, making fun. That's what a parody is, after all. I am a little confused on the message you are trying to send with this "parody", unless it's not a parody at all and you're just using the word to dodge bullets.
The camera moved around far too much. I really don't think it's a good idea to change your focus so much.
I do agree with previous reviews that the animation was a bit lackluster, and the video as a whole failed to grip my attention. In fact, the first time I watched this, I was unable to maintain focus on the video and had to watch it again to catch everything.
I won't nitpick on physics, since both your inspiration materials kind of laugh in the face of it anyway.
However, there seems to be some pointless action interjected in an attempt to make the video interesting, like the...I assume the character in blue is the protagonist. Well, he for no apparent reason made that fast-paced multiple walljump out of the pit that had been created by the Tetris blocks. As no more blocks were falling, I just didn't see a need for it.
The sudden cutoff from the music is also a bit of an annoyance. Try a more gentle fade in the future.
Like I said before, it was an admirable attempt, but there is just a lot you can improve on with it. A lot.
Also, try not to break the fourth wall unless you plan for there not to be one.
