I love the art style y'all got going on! Y'awls thumbnail caught my attention and had to give it a try.
As others would say, it would be cool to see dialogue, or some sort of progression system for dealing with them bullets. Also, are you able to move? Either way, I thought not moving would be a deterrent for myself, but it would be cool to see how you'd develop the game and give tools to the player to deal with not moving (e.g., defense towers, barriers, etc.).
Either way, neat lil' game and keep it up!
