First of all - thanx for that amazing game. I like the idea very much. But there are few questions:

1. How do I merge few farms/rooms into one? There are many times I want to expand area of filed or room. How to do that?
2. How do I enter city from global map? I build few cities but for some reason can only enter the last one?
3. Currently there are very few researches in research tree. Are there ways to unlock more or this is it for nw?
4. How to edit room after it was build?
5. Diplomacy and battles. Are there any? Is is available in current free version? If yes - then I want buttles, how do I go about io

Hi there, thanks for playing. Unfortunately when you've finished building a room, it is fixed. This is for a number of reasons and it's quite hard to fix, but more than you have asked for it, so I guess I'll have to fix it some day.

Research, yes it's all I got, but they can be added by anyone in a file and it's very simple. Of course more should be added, I just haven't gotten arround to it.

Right now the world map serves little purpose and the engine only supports one city at a time. This will be fixed in the future.

No battles or diplomacy yet, but on its way.

I suppose this can be done using mod-file? Do you have info on mod-file format?

Yes, sure!

It's a file in res/data/definitions called Tech.txt 

It is a text file in JSON format. First all the available bonuses are listed and you can't add or remove any of those, but you can change de name and description. Then comes the technologies.  ( TECH: [...] )

Here you can add or remove techs. To add one, simply copy a clause and fill in the information. It could be tricky if you've never done anything like it, but very simple if dealt with JSON before. 

After techs have been added you must visit the race file in res/data/race/Dondorian.txt and add the keys of your new techs in the TECHNOLOGIES: clause 

Then you're done. Unfortunately, it is not save game compatible, so you'll need to make a new game after changing this stuff. I will change that. I will also make a much more extensive guide some day :) Good luck, don't hesitate to ask again if you need to.

P.S. If you manage to add any technologies, I'd love to see them!
