After the updates in the past few months (AI levels, leaderboards, achievements, etc.) our top priority now is online multi-player. This is a big thing for us and we'll require probably 3 months for this, details will come out in a few weeks. Game's release is planned on May 2016 with online multi-player built-in. Early Access has extended (was planned to end in December 2015), but we believe that's a good thing.
You'll be able to play online friendly matches with your friends or unknown players on Steam. Possibly mixing local and online multi-player. So for example 2 players at one PC could play against other 2 players over the Internet. Matches 5 vs 5 should be possible too. That's the plan, hopefully will be realized fully and in time. You'll be notified about any progress soon.
Note, that we'll develop other features and fixes too in this time, but these may be published less often from now on. Possible features are new super-moves, as these are relatively 'cheap' to implement and goal replays as a byproduct of online multi-player.
In the meantime you can talk about Kopanito with your friends, try local multi-player with them, maybe organize a tournament during a party. This way you'll be able to post better feedback to us and promote the game a little, which is important too.
