Nice job, this game feels really polished! I like the minimalist artstyle. The sound effects work well with it too.
I wish the game was a little harder! My go-to strategy was to move back and forth in a save spot with each dot to let the others reach their goal. Maybe you could keep dots from doubling back on their own paths, add a score system that decreases with each turn, or design levels in such a way that there aren't many safe spots.
