I found difficult play and find games where I can play (I am Spanish) because all games are full of English players. Most of time, I get kicked only for communciation difficulties (Maybe 1 of 5 games people tolerate play with a non-english player). Maybe you can add some features to search games or filters for country (if game creator considerates essential the language) to avoid losing time being kicked after enter and start a game. Maybe add some pre-constructed phrases that I can select in the menu and each player can see in their language to allow an easy communication.
Other feature that can be interesting it the option to see a grid in the table when you pick an enemy, this can make more easy count the distance between they and my players.
There are a lot of content with subtitles (like the intro), but when I start of end a map level, the narrator voice are not subtitled and I can't understand what are saying.
Thanks!
