I really liked your game! It totally reminded me of Hotline Miami, and the final boss was giving me Binding of Isaac vibes. I genuinely enjoyed it! I also got spooked when an enemy suddenly popped out from around the corner, haha—super good! The sound is cool too, and I love that you added a little reload animation for the gun; that was great.
I only had two minor issues, nothing major, just giving you a heads-up: sometimes a small enemy would just stop and wouldn't chase me anymore. The other one was that the death animation played, but I didn't actually die, so I ended up having to restart the game.
Overall though, it was a great game, congrats!
