Nice take on an Asteroids-style arcade game! Customizing your own ship always feels fun and meaningful.
It's been a while since I've played a game like this, so it took some time getting used to the controls. I found it pretty tricky to hit targets with the gun. With my direction movement in addition to the enemy's, it was difficult to lead shots and get hits in. Most of what I did get just seemed to be luck.
There's definitely a really fun idea in here. Nice work!
