Thanks. I am in a bit of a wrestling match with the WebGL. I can't work out why it chops. On my PC I get a framerate of av 700 fps in editor with no profiler peaks. The WebGL is limited to 60 fps but then has a stutter every now and then. I can't seem to work out what it is. It is not a problem in the windows version. Yes some levels have been updated and some extra ones slotted in to help with the learning curve. It gets more interesting when the bombs come into play...they are sensitive.
