controls work, but they're difficult to use. WASD would've been a better choice for movement instead of the arrow keys
very lacking in visual appeal; it would have been nice to at least have more than just a solid colour for the background
i'm not sure if that's by design, but enemies seem to require a random amount of shots to kill
when an enemy hits the player, it is not immediately clear that the game is over as i can still control my character as normal
i've seen games that are a lot worse than this, but don't take that as a compliment
