>>12095120I already made these suggestions to the last person who wanted to work on gen 3's map but never did it. But anyways...
Switch the fly and strength TMs. You don't get fly until the sixth gym and you get strength around the second or third, yet you don't NEED strength until after the sixth gym. If you just switched those around it would VASTLY cut down on backtracking and wouldn't change a thing, except one optional boulder in fiery path.
Also the ledge south of meteor falls to rustboro KILL IT WITH FIRE. The ledge south of mt. pyre to route 123 KILL IT WITH FIRE. even that ledge that is in the town with the hot springs, that makes you take the gondolla up the mountain if you jump over it, KILL IT WITH FIRE.
That part where you have to go back to fight your dad, and have to take the long way unless you know about the surfing shortcut in oldale. Remove it. Or make the shortcut to oldale much more conspicuous so you won't just easily pass over it. Or take my suggestion of giving you fly earlier.
If you want to be really ambitious, add some bridges across water routes so they will be optional, maybe you can add some aggravating trainers on those bridges, but I'd enjoy the game a lot more.
