Although I've already expressed my views pretty adequately in the chatroom, I thought I may as well chip in my two cents here too.
I think that the glitch with Tails that can cause single rings to double-register should definitely be banned from the competition, as it clearly violates the general competition rule, "For ring stats, you may not collect the same ring(s) more than once", and if this rule is currently in effect for every game on the site, I don't see why an exception should be made for this particular game. If maxing the game's ring charts turned from "Collect every ring in the level" to "Collect every ring in the level whilst tediously glitching every glitch-able ring", it would severely detract from the competition in my opinion, and players would be discouraged from competing, because â€“ let's face it â€“ who wants to spend their time painstakingly glitching rings? As I've clearly said in the chatroom, I don't plan on competing in this game any time soon, but candidly, for the good of TSC's competitive nature, I think that this glitch should be forbidden and burned to a stake! BURN THE GLITCH!! *shot*
On the subject of playing as Tails with Sonic, I don't think that this should be allowed either (that is, if we decide to prohibit the aforementioned glitch); players could inadvertently execute the glitch and accidentally obtain illegal stats, which would have to be removed from the charts upon submission. My current track of thinking is that, if playing as Tails with Sonic is banned, people won't have the ability to accidentally perform the glitch in the first place, and thus nobody will unintentionally obtain rule-breaking stats, so no complications will occur. That's about it from me on the matter, so hopefully we'll see what some more of the other users have to chime in.
