The controls are really strange and feel like a throwback to the past. Why not make the wasd keys move the player and let us shoot using the mouse? I can't think of any reason not to.
The game is needlessly tricky. It's a shame because it looks and sounds great and very creatively fits the theme so well. Please just fix the controls and you could have a really interesting and fun game. It pains me to see something amazing falter on such a minor problem that's just a bizarre design choice.
