Wow that song is catchy and goes for so loong ! It's neat, i like the little space station as well. I like that you used this specific shape, instead of a circle, it gets challenging to handle ennemies coming from the sides. Raming the ennemies felt fun too. I struggled a bit to use the turret, since there is not much time to react to a wave (at least on the small ennemies)
Overall cool game
