Was thinking this would be one of this regular find a path games at first, but when you start having to figure out paths simultaneously with different colors by restricting movement with certain ones to progress others... that really upped the challenge! Clever twist.
I feel like the ads and logo get in the way of the experience a bit sometimes, but apart from that it's a well-thought out game. Just the right amount of difficulty too, enough to take a while but not for you to give up on. Nice work.
