Patch 1.2.1

Fixed bug where the boss in World 3 would sometimes play the wrong animation. - Fixed bug where the player would collide with an invisible wall near the second tree of stage 1-3. - Fixed bug where grappling into "hangpoles" or "hangbats" very quickly twice in a row would make Sami get frozen in the air. - Fixed small visual glitch on a shadow on stage 1-6 when playing on low quality settings. - Made sure that all rotating objects in stage 5-5 get reset to their original rotation every time the stage is restarted. - Fixed bug where Sami would go inside the wall at the very end of stage 5-2. - Fixed wrong shadow at the start of stage 1-8 when playing as Sami. - Slightly moved jump bumper on stage 4-S1 to facilitate a very tricky jump.
