I am very sad about losing Stormside, but I'm really enjoying this game anyway. Atemsiel knows how to make games and he knows how to write dialogue.
I'm not sure if he ever lurks these threads, but I have one easy suggestion for improving the immersion. Mila is a relatively poor girl in a relatively poor Russian speaking country, but her English ability is as good as someone who grew up as a middle class native English speaker in the UK. There are some obvious grammar issues that Russians tend to have when they speak English, and Mila would be more believable if she had them.
Most obviously, Russians often have trouble with prepositions, verb tenses, word order, gendering too many nouns, and using articles like "the" or "a" or "an." Russian is structured differently and doesn't use articles. So you hear things like "I graduate college at 2024." "It will be cost about 500 dollars." "It is popular tv show that my friend recommended me." "I love to cooking." "She is same age like me."
English is a difficult language, and I'm amazed people around the world learn it as well as they do. Still, a native Russian speaker who has never left Kharzovya is not going to sound like a suburban American or Brit.
Just a thought
