Well, I feel the new world record revealed Mega's stance on this. Feel free to sent your Booster runs guys.
It may be the case. Recently King have the habit of throwing free boosters in the levels, which is why I believe we should had an Booster and Boosterless subcategory :p
I think lv. 50 had been chosen as the Misc. cap because lv. 50 was originaly the last level of the game. It's not that complicated to achieve within 5 lives ether (espically if boosters are allowed), only lv. 33 really pose a real threat in that sense. As a matter of fact I planned to give it a go one day when I'll wont be too busy with school.
I think that removing it is a bit excessive, perhaps retiming it is more appropriate. But I notice I'm kinda late to tell that since it's already remove :p
But to answer your question, the HTML version is by far faster than the Flash version because of the candy falling speed have been increased. By far as I know the HTML 5 and mobile version are more or less the same, so I would say only Flash is slower.
It had come to my attention that the weekly booster bonus (Monty's and the alien's event) has arrived in the HTML 5 version as well as being already present in Android / iOS. Since those are not bypassable by my knowledge, wouldn't it be wise to separate the caterogies by Boosterless / Booster No IGP? I mean boosters in most of the levels are significent advantage over "boosterless" even as early as lv. 7 and the entire board have boosterless runs (I think).
I'm EDav1123, I've been watching TAS and speedruns for about 4 years now and I've decide to give it a try. I'll be thankfull if you guys suggest me a good video capture software.
