So I downloaded game okay, it's a great concept I love the idea of mining materials to feed your tower defence, and its also very good that its so open on huge islands and such, but you really need to add some tooltip info about which weapon types accept which materials and such, also info on what certain elements do, like the router for example - to hell if I know what that might do :D really a good idea and great concept, just give us a short tutorial or tips so we can easily start out.
