Thanks for the response. I don't really know if you've unlocked all ships, cause it doesn't depend on your score if they appear or not, but on the wave number, which is not displayed to the player.
Yes, the sounds effects are bfxr, lol.
I might've improved the movement since you last played the game, but I don't remember.
It's kind of by design, but the way their crosshair moves is very bad at the moment, I should improve it, but I don't know how.
