I like roguelike games, recently searching for one, I found your game. I would be very happy to translate to Spanish (or at least try it, my English level not is high) because there are few games of this kind in Spanish language. Is it possible to include language support for this?

It is certainly planned. I just need to load all the text from files rather than have it hard-coded. Right now, the only thing that can be reliably translated are the items. 

I think translating the game as it develops is better, more people can know the game, more people report bugs, more people give suggestions, etc.

I know how difficult it is to add a support for more languages, so I would not expect it to be implemented for some time, I would like to start translating the texts I see inside the game or the list of items.

Been doing lots of work on moving objects from data to an "ID" system to allow better translation support. So far all that's left is the UI and main dialogue of the game.
