First of all,this is a nick arcade prototype of  the hit title Sonic the hedgehog 2. This was shown in a tech demo at E.3 and  Nickelodeon. if you noticed any glitches in the game it is mostly from programming errors. Anyways this is not the sonic game your`e thinking of. It seems lame at first,but you will catch on to it. I think Sega might have been trying to change sonic the hedgehog`s game play style. Also if you only have Sonic 2 on any console or p.c if you go to 2 player mode with debug mode you cant go through loops like you normally do. Overall i think Sega did a great job both on the final copy and the prototype copy. Also for a interesting fact if you go to the sound test in Sonic 2 listen to a certain tracks you can hear the prototype hidden palace zone theme. ( i am not telling the song no. so you can find out your self I hope you enjoy playing this game.
