Really enjoyed this! Managed to get just over 12k points before I died. Sound and graphics were super cool.
I agree with some of the other feedback. Enemies should have been easier to kill, and they should have spawned more quickly to increase the pace of the game. Probably would have allowed you to increase the movement speed by just a bit as well, which would have been pretty fun I think. Also not having a longer indicator of aim (like a flashlight effect or a laser pointer) made it awkward when I moved into areas where the camera wasn't following me (close to the level edges). Overall had a ton of fun!
