Really cool game! The art is nice, although the background objects are maybe too bright to my taste, I sometimes lost focus on my ship haha. I think you should later add some sound effects to make it even more pleasing. The enemies are a bit too difficult, when I thought I lost one and was too far from him, I started mining and he rushed at me and killed me haha. Maybe make the enemies return to their initial location or remove them when the player is at a certain distance?

Good job!
