On the second level it doesn't look like he puts coils on square area on the left. Should it work?

For some reason I couldn't get past level 2 - there's no indication that I've put a right color in the thingie on the right, and I don't seem to get it open whatever colors I put in.

Still, I liked the concept and enjoyed visuals and the soundtrack :) You should carry on working the concept, it has the potential.
