What a fun game! I love the old school feel, the encouraging voice over, and I really love the ship you are in!
I also love your cover picture for the game. This is one of those times I wish we could give a 4.5 or something for overall. You deserve it.
I did find a bug in it. It gets stuck if the enemies fly behind you. They do not return and the game does not seem to be able to move on to a new wave unless you kill them all?
You should check out ours. We have a common theme, though you are out in space and you have a great voice over. They say "Great minds think alike" :)
Thanks for sharing this game. You did an amazing job.
