I'm playing metroid again and I get traped in skytown here is why: I was in the bomb part and I had to grab the 2nd part of the bomb but I wanted to stop playing in that moment so I went to a saving room after some spinning plataform that you just can reache making the spinnig stuff in the air. then when I start playing again I couldn't go back because when I did the spinning in the air stuff I couldn't reached the plataform and for continue into the other rooms I have to upgrade my weapon so I REALLY DON'T KNOW WHAT TO DO! I just don't want to erase my slot and replay the game AGAIN!
