No, i think that, at this point, i screw something up when relasing the game or something like it, and that it wasn't a glith at all... For what i know, I think it can easly be that i playied my game too much and i adapted to my own game's phasing (and not reconizing that it was slow, at all)... That's good to know that wasn't a bug...
Anyway, i'll fix the moviment issues on a next build!!! Thanks for the feedback, it really means a lot to me!! =D
