Fun fact: When I played sonic 1 on my 2DS and mobile I got stuck on Marble zone and 2 other zones. Sonic 1 was in Sonic collection 4 games in 1. :D Sonic 1 is on the switch so I might get it. Also pls follow @Turtlefanscratcher and (me) @Ca44183. You don't have to if you don't want to. Just saying.
Backdrop is made by me. Marble Zone music belongs to Sega. Sonic as a cat belongs to me. :D All rights reserved. :D
