I liked it. i could play on the trackpad of my macos without problem. its rare in shooters. wll belanced controls. for a feeedback: it could be more realsitic in exploration, less linear, more explorative, less about move/shoot/reload sequence as it gets boring, better particles, and zombies movement speed and animation synced. but overally it is a a good direction, i can see it growing into a great game with more time.
