When you reach Garloz (the overhead view level), you can get on top of the grassy areas that normally aren't accessible. From the first starting point, walk up and take a left, then walk up and take the right path when you come to the fork in the road. When you reach a dead end to where you can only move to the right which takes you to the next screen, hold up and get next to the dirt wall. Move to the right and press up on the next screen, Rygar should walk up a little bit. Walk back to the left and you'll be on the wall, so hold up again and Rygar should walk up even more. Walk back to the right and hold up. Rygar should be on the grass now. If you walk to the left again you'll be on top of the wall. From here, you can explore areas of Garloz that you're not supposed to be in. The map gets pretty glitchy over here and you can end up dying if you to another screen, so always be sure you are jumping in mid-air should you choose to enter another area. For you might not be standing on solid ground when the screen scrolls over.
