Fun little game, well done! The amount owed it crazy 😂I thought I had it but hadn't realized that the numbers are both centered so I'm not just missing a 1 in front but also a 0 in the back.
Feedback for improvement. I instinctively wanted to turn the shop with A and D (or alternatively Q and E). Took me quite a while to get used to turning it with my mouse. It's also unintuitive to click on an asteroid and then hold mouse to fire the laser. It might be more fun to fire the laser any time with mouse but having to aim with WASD. Standing still with E is a huge help, on the other hand this could be an upgrade as it would make sense for a crappy ship to drift a little while mining.
One thing that I found weird is how the laser works when something is in front of the marked target.
