Everybody, Thank you for feedback!
Matthias Schedel, yes. It's very unclear, but you can attack enemies with you Drill('1') or place turrets, other thing - you can grab enemy and throw them at the station(station destroys everything that hits it)
knexer, Great points! - I should provide some visual feedback to attacks. - Also, I should make some sort of soft tutorial for tools switching and grab mechanics. - At first, asteroids damage everithing based on their speed. But before release I turned this off because it was making game a lot more chaotic(even now it's pretty chaotic). - Station is designed to destroy asteroids on collision and gather all the resources. - There are 3 types of asteroids, based on their 'richness'. The bigger it in size and the more bluish thing it has, the more resources it provides.
Thanks again, Feedback helped me realize what I need to improve the most.
