Hmm, I don't think we've ever spoken face-to-face, as it were, but I'm pretty sure I've seen you before when I was a lurker. Either ways, welcome back!
another bug or glitch ... I know it's a weird gravity if you ride on a shell but I guess it has to explode when the shell crashed with the wall...doesn't it? O.o
I remember trying to ride it backwards the way Rayman came, arcing it around into that pillar of lava at the very start and trying to fly it back up. It took me quite some time of foolhardy trying before I realised I wouldn't be able to do it and gave up. That must've taken the guys and gals at UbiSoft quite some testing to get foolproof!
I just had a glitch when playing Rayman Legends for my walkthrough (but had to restart the level because of it): I see the Teensie King out of its cage waving to me in a Moskito level. And this without me having done anything before. As a result, it only counted the Queen and the Jester-hat Teensie. It was odd.
