This totally took me back to my Atari days and my grandmother yelling at me to turn down the TV because the sound effects were driving her mad. Ha! I enjoyed the whole aesthetic of this game. I did find it pretty difficult, very fast. The rate of fire felt a bit too slow for me. I'm not sure if anything shows up later (since I die pretty fast), but some collectibles that change the ship and weapon properties could help shake up the strategy of defending the hole.
