Someone called Александр Кулаков got in touch with me recently and kindly provided a translation of the game into Russian, which I've now made available in the latest patch! So, if you happen to speak Russian, go check it out.
(Note: It's possible this isn't the final version, we may make corrections and improvements over time).
If you're a fan who is interested in translating the game into another language, do get in touch. Be aware it's quite a big job though - about 45,000 words, or 4300 lines.
Meanwhile work continues on online co-op :)
