I dont see any progress being kept between games. All you do is upgrade between rounds like any normal game. Unless I have to get to like wave 100 to unlock perma upgrades or there is a upgrade menu hiding somewhere?

Movement appears to be car-like instead of spaceship-like. In Asteroids, to move forward you thrust for a moment, but when you stop thrusting, you keep moving, as in space. In this game, you only move forward when you press forward, and when you release the key, you stop moving. This isn't like Asteroids at all....

Game would be a lot more fun if each weapon auto-attacked. Holding down 4 buttons is not fun

Anyway to enable V-sync

game loads, I see made with unity, unity fades away and game crashes
