Great job! The gameplay loop is a bit simple, but it's very well done. Visually, I love the enemy design and the use of shadows to create a sense of unease. As far as mechanics go, enemy movement was unpredictable enough to keeping the shooting difficult and enjoyable. I loved the escalation as more foes begin to appear, forcing you to shoot, reload, and immediately fire again, and the rhythm I was able to fall into. Since I could see most of the map from atop the rock, sometimes my strategy devolved into standing there and spinning to shoot things, so a future addition may benefit from more obstacles or trees lying around. It may force the player to maneuver around slightly more. I definitely enjoyed this experience.
