Glad you liked it.
Yeah I kind of programmed the asteroids because I get side-tracked by vaguely interesting problems, and then realised I didn't have much to do with them, I did consider making it into a mining game also. If I were to expand the game I'd probably use the same code for ablative armour panels on certain enemy types, or for doors in a megastructure dungeon of some kind, etc.
The cutscene is a result of me discovering tweens about 2 weeks before demoday, and there's a ton of signals going on for spawning the ship etc, there is an option to skip the intro in the settings but not during the cutscene itself
