Will check it out once I have the time. I think it’s very easy to overlook something with these kind of things, that’s also a part that makes it interesting. 
A scratch style interface would definitely make the game accesible to more players. I’m thinking of doing something like that at some point while also allowing javascript for those who don’t really like visual programming. Then write that stuff to javascript so that the experience is more the same. It only seems that the UI part is going to be a lot of work. For now, I’m allowing scripts to be loaded from file so that you can use any external editor that you like. I might try something turn based as well so that it’s more part of the flow to program, validate, then try a match. It will also prevent some timing issues that I foresee popping up in the future. Though, for now, I’m continuing with this base defense idea and see where that goes.
