Hell yeah this kinda game rules. My suggestion would be to make the gun mechanics have a little more nuance. Like ammo or cooldown or something. The way it is now there was very little reason not to just keep the mouse button held down. Which meant that rather than running and dodging I was slowly inching down hallways, spraying left to right, and nothing got close. And then I pressed esc on the boss battle and the game crashed. It's a shame because I could tell that the boss battle, by being more open, was solving that issue by removing an easy choke point.
