Oh, I'm perfectly calm. Believe me, I have learned to step out of internet arguments when I can't be rational about them. But you don't know how much effort the author put into the recreation. When I made my own implementation of the drop dash, Mania wasn't out yet. I had to frame-advance through 60fps YouTube footage to determine stuff like the release speed and camera delay, and even added details like having the dust track the height of any moving platform you land on so the sprites stay lined up properly. It was not a half-hour job and you can't pretend to know how much work went into it from simply playing the final product. A better metric which was brought up earlier, is the the number of practical changes made to the base game. By that measure, if the submitted entry is just Sonic 1/2/3 with the drop dash, but with otherwise the same levels, the same graphics, the same music, the same gameplay, then it should not be accepted into the contest regardless by which means it was accomplished. The average playtester isn't going to know or care either way.
