The animation was planned from the beginning, but was cut due to time restraints and the lack of foresight that would need the gamestate to be computed in steps interleaved with the animation playing, and this was a refactor i couldn't risk at that stage.
I plan to refactor this after the jam and add some animations that would make the purpose even more clear (clearing a row gives small score, connecting the sources gives a huge score, also a highscore feature would highlight this. Or a win condition of connecting sources above a certain level?)
