No way to switch it to English language. Why do developers keep doing this? A the very least it should respect the browser's 'preferred language' settings. Don't just guess by the OS locale without any means of changing the language.
Please, don't make games that select language for you with no way to change it. If my IP/browser locale is not English it does not mean that I understand the language this game assumed I would prefer.
I find it extremely annoying when the game chooses its language based on my IP/system settings and does not allow me to change it. If I cannot play it in English, then I just won't play it at all.
