Fantastic idea. There were many games of this type, I remember Zenji for Atari and C64. But this one is a bit different, because it more like puzzle. Looks super cool. Some leves are quite easy, some are tricky. If there were more colors or bigger board, it could be even more challenging. I found a little bug. When the game is started, sometimes a sound from the title music stays in the background and never stops.
