I love how this game looks! The sounds can get a little annoying (specifically just the enemy spawning (?) "woo woo" sound) but it's nice to have the options to turn them off. The only real complaint I have as a player is that the ship moves a bit slowly to dodge enemy bullets. Also I was forced to use WASD because the arrow keys would scroll my browser around in addition to moving my spaceship. Maybe that's just a Chrome issue.
I had fun!
