Love these types of puzzles, challenging but still very logical. ( the music was relaxing :D )
I was able to complete a map, but the end screen did not show - I am guessing since it's randomly generated, it can generate a map on where there are more than one way to solve it?
Well.. It's as you said)
But in your case - it's really not solved
In right corner there's a piece of road not connected to anything
But yeah.. It may be a bit frustrating
I see! it's the 2 pieces that should've been swapped, still a good game :)
