Really awsome speed based shooter game. Only thing that kinda bothered me was it seems likle the run slide mechanic is pretty hit or miss. Sometimes I go to slide and I just crouch. Sometimes I go to crouch and I end up sliding out of cover.
Very cool idea, fast forward and some indicator of what a tower would cost before researching would be nice. Maybe a feature to queue what your next tower or action would be since building, recycling, and researching takes time.
