This is a pretty cool asteroids game, though I'm not sure I got a hang of the towers. I would have liked to be able to hit the asteroids from farther away, especially because they seemed to spawn fairly equidistant from the base and so would all arrive at about the same time. The other issue I encountered was there didn't seem to be a way out of the controls screen. I think a great way to further develop this would be to figure out a minimap, maybe something like in elite dangerous, especially as the asteroids could sometimes be lost in shadow. All that said, this was a really cool submission and a great space game foundation. Nice job!
