This game is already on sale!
I would like it to receive a massive support, since it's a good game and it's been lovingly created by the devs just for the fans! Remember that this all started as an April fools' joke: the devs had to do some tests in UE4 and used the concept and some characters from their old game (Street Fighter EX), but eventually created a game, since the trailer received so much acclaim...
It's a little studio without a high budget, but they managed to recover many characters and they are planning to add more if sales go well.
This video is a bit old, but it's an overall review of the story of the game, the gameplay and the Gougi system:
