This LCD I had the actual physical device. I forgot how horrible these were to use, with screens that are very difficult to see so you need bright light, but then the bright light causes a lot of glare on the screen you you can’t see what’s happening due to that. They really are a nightmare to use.
The Sonic 3 LCD is similar to the previous ones, move to the right and defeat enemies until you get to the end of the level. In this, you’ll sometimes fall in water and need to jump out before a timer runs out. There’s no way to see which sections of the level are gaps you can fall down or walk across. I found that just mashing right, up and attack would work for getting through most of the game.
