I wish I could set the mouse speed more exactly, 2 feels too slow and 3 feels slightly too fast for me.
The controls feel just right and exactly as I would expect. I think adding a bit more friction would be an improvement, it (very slightly) feels like I'm on ice.
Enemies could have flashier muzzle flashes, they look like peashooters.
The fun factor already improved 10x from the previous demo day since the enemies aren't utterly useless, I had fun with it and shooting feels very satisfying.
