Cool idea! The potential is there. I like that you have different colored spaces for each of the characters to step on, which can create some moments of tension with the separation timer and getting the correct colored character on the tile. But instead of dealing with that tension, I started joining the characters on the same tile and slowly moving whatever character was needed for the next one. Perhaps if there was a consequence for having them on the same tile for too long? I don't know, but I think you are on the right track for something. Great job!
