I'm glad you liked it!
Since we're at the end of the jam, I think it's fair to share the ending details. Endings 1 & 2 depend on whether you have more or less than 2500 total credits by the end of the 3rd mission (whether you earned enough to pay your debt). The third ending is hinted at in the text of the other two but I figured nobody would find it since it's pretty obtuse. Those two imply there are no more shooting stars because hunters like you mined them all so the third ending is triggered if you refuse to participate in all three bounties by immediately skipping them from the pause menu. It's a "the only way to win is not to play" situation.
I'm surprised someone noticed the enemy AI trickery I'm doing (for better or worse)! I cheesed the enemy AI to make it easier to get done in time. The fighters are pretty dumb and just try to follow an orbit around the player that's configurable per mission. Each fighter offsets its orbit by a random amount from the center of the player's screen which is what causes them to dodge when the player turns toward them.
For the shooting, fighters will constantly shoot at your anticipated location but only while they're off-screen. I did that so I didn't have to worry about making their shooting look good. I wanted the game to feel more frantic than it was so their gun has such a high spread that it's almost guaranteed to miss; however, they will periodically fire a single projectile with 100% accuracy. It takes about half a second for them to refresh your anticipated location so it's harder for them to hit you if you're constantly changing speed and turning. The ones on mission 3 are harder to avoid because they're set to orbit closer and the game's director allows almost twice as many be spawned at once.
