I am playing the earliest prototype of Sonic 3. Just messing around, having fun. I played through Carnival Night because I want to try to record it. Will have to play through a couple times. I put in a code where it enables Knuckles cut-scene and it glitched out. I went to the end and fought the boss and the screen locked. In this prototype many of the levels and in between zones are impassable. So I used a screen unlock code. The level just ends but there is a hole to jump down!! It goes in a never ending loop. I thought it was funny so made a video. I think I will do that from time to time in these prototypes or when I'm messing with debug/something funny/weird comes up.
