Awesome !
5, 10 and fav for this awesome and funny work on the song.
You've got a peculiar way of singing. Ha ha, that's absolutely fantastic, and that suits totally perfectly to the music. Great lyrics, great way to throw them on this short song. I'm sure it's hard to deliberately sing with a delayed flow and trying not to be too melodious while still being.
It's an awesome work you gave here, and you are all very good.
The result is really of high quality, and i salute the success of such an exercise (even if I got the feeling that you are used to do such songs.)
Also, great job on those littles parts in the middle and the end where you just talk after the big 8bit noises, that is contributing to the humor and made me even laugh.
Another point which is noticeable and that gives evidence of your great job is your choice in the parts of the song that must have been sang, talked, or used as ambient to install your background noises and kind of theatrical actions.
I guess there is nothing to improve on the song. Yes actually, one thing, turning the volume of the song a little up, cause it's a bit erased by your loud voices. It's not disturbing for the fight 8bit sounds, cause it breaks with the song, but I guess you should try to lower your voices.
For your next songs, just a clue : you are not forced to sing the same melody as the main theme, and using the voice as another melodic line is sometimes really benefic, giving the song a bit more density. No problem here, it is really perfect. Super original and well done.
