What I loved from the start was the music and dialogue. It reminded me of Fire Emblem for some reason, but to me that's a good thing. The gameplay, while not reminiscent of Fire Emblem, is still great!
Just some suggestions for improvment: Keybindings or alternate control scheme, I prefer ASWD, or better yet mouse for shooting and ASWD for moving. Second, a pause button and clicking outside the box pausing it. Otherwise, it's a solid game.
