First step on global map

Don't be afraid! It is my draft. It wouldn't be this way in the game!
This is a draft of future global map of Frontier, the underground catacombs. They are waiting for you to explore them.
Right, it is vertical map.
This map doesn't look really big, but I have limited to one screen size with a purpose.
It is easy to test.
Also, every time you enter a local map you will have relatively huge local map to explore with towns, farms, buildings, monsters and so on.

On this draft you can see an orange creature - it is a player.
Ladder like "things" are pipeline lifts. Huge ancient mechanisms of strange origin. They constantly move in catacombs and used by humans to move all around the Frontier.

You can travel via lifts to another levels (vertically), but can leave lift when it crosses real level (obvious).
To travel horizontally you have to enter local map and find tunnel to nearby catacomb. Once found it and reveal a part of dungeon out of fog of war you can travel freely via global map.

Next step is to tune map generator to create different type of local maps.
It means you will see a preview of essential features this level would has. Like settlement, monsters activity and so on. This preview is to be a seed for a map generator.
So you can expect to meet huge mushroom forests, monsters nests and underground cities etc.

PS
Global map layout isn't generated, but hardcoded. It is okay. I have set it as a different and interesting goal.
