Many ears enjoy your remix. The problem, however, is there isn't enough impact. Add more instruments that have the coveted "POW" factor, and make it decently louder. I feel that a badass young mouse composed this. Nonetheless, I do like it.
I implore you to make a revamped version, of your version, of Wacky Workbench. Keep the 70's feel. You have the potential to be the best remixer of this VGM in all the cyberland of Newgrounds, comrade. Good luck and good work.
