I doubt you would wanna explore the whole map. The whole map would be larger then the one in zelda: parallel worlds.
Then I still want to explore the entire map. Am I right to assume that the world is more like that of Zelda II, Final Fantasy and Golden Sun? Where you have a big overworld with random encounters with enemies and rather featureless. And only a few areas are worked out in detail. If not then I would like to explore the entire thing.
Thats why ive been thinking of adding a train system, to each town. The trains would be fuelled by these newly discoverd energy cristals. Each town would have a train stadtion, each with its own little sidequest to activate the cristal in them.
Could work as some fixed teleportation system. But be carefull that you won't get a dungeon crawler principle.
P.S. small upadate: Is this better?
It looks good, but the water is rather crowded. It has to many white lines. You might want go with very clear water that you can see what is in it. But the white lines make it rather difficult to see what is in it. Also understand that when making clear water, you need to show what is in it. Otherwise it will look very empty. The idea I get with so many white lines is that the water is rather rough with a lot of waves and has a violent currents like in oceans.
The ice is a bit to grey. Ice has always been more white with soft streaks of grey and blue (very light grey and blue). My advice is that you look at TMC's Temple of Droplets and ALttP's Ice Palace on how to do ice.
Well that is my advice for this time. Keep up the good work you're doing great.
