The V1 tried to combine real time gameplay and strategic thinking, so i added tooltips, highlights, etc.. to try to make that work. In v3 the two things are separated, and I tried to focus on mobile gameplay, with the desktop version being basically a scaled up mobile screen. There should be audio in both, what browser are you using ? The v1 had performance issues because of the use of a lot of css combined with canvas, the v2 is pure canvas and performs much more smoothly on low end devices. My focus for v3 was to make it fun and challenging for me to play it, while still being approachable for my girlfriend, who just wants something chill to play with and has no interest in high scores.
