This is a hastily emscripted version of my LD47 #27 game, "Not the blue wire!".
WebGL doesn't seem to support thick lines, and there's no audio. Gameplay is (otherwise) the same.
The windows binary is the preferred version due to these differences.
Tested working on firefox and chrome on windows and safari on osx - on osx you need to enable WebGL from Develop->Enable WebGL.
