Rad game! Felt really good to play, movement was solid and shooting felt good. I liked the various guns, and hacking was a neat mechanic. Only bits I can complain about are the lack of a sound effect for the shotgun and it being hard to tell which ledges are okay to walk on at times. Oh, and I wish the after wave report said which wave it was, so that I could more easily tell how close I am to beating my old score.
