You got me a bit confused here, but if I'm right you can only build on the black squares with blue edges?
If yes, I like the map. The path is nice, it's short but why not, I like the design, little bit Handy inspired perhaps
The only thing i dont like is creeps going from right to left for the upper team...the standard is left to right for upper and right to left for the team below, I wouldn't go against that tradition. Probably you should flip the path horizontally and move the On button with it?
That would be the only thing I have to say here

Keep on creepin'
