Thank you for playing the game. I am happy you liked it.
I am not sure about making a paid version of the game, but there will most likely come a updated version. First of all is the plans to give it controller support, settings menu, improved UI, and some improvements to the music/sounds/visuals. I also have some ideas to at least a couple more game modes, that is using some of the game mechanics.
I will keep it as a local multiplayer game and I am not sure how well a tournament would work for that. But maybe.
