Hey Patrice, thank you very much for playing and giving us feedbacks :) !! We are planning some new mechanics for that timer!!! And that's a good idea btw, the restart button, gonna discuss about that with the team!! And about the colors at first it was just a art design. But now we are implementing some unique mechanics for each block, for example the red one already have its own mechanic, when you plot it, it becomes part of the map (a gray block).
