My advice to Vostok Games is that if you want to keep updating the game and make it worthwhile: Add a mode with bots.
The player base isn't strong enough now and will dwindle even further in the next couple of weeks, but that mode will ensure there is a base for people to come back through the updates (without having to sit through 30 minute waits, or even not being able to play at all) and eventually, through their experience in that mode and word of mouth, give another chance in multiplayer.
I know it's not easy and it is costly but updates aren't going to be worth anything if people can't join a single game.
Hopefully you take this game seriously as I am very dissapointed with the end result. Keep working hard and it will pay off tho.
