Didn't make it in time

The game was done except for two things: 1. There was a bug I had to figure out that took me past the deadline 2. There is no balance testing so I don't know how easy or hard the game is
But the idea was simply that a space ship of doom was heading toward Earth to destroy it. You can take out its engines temporarily to buy yourself more time but they will be repaired again after a while. Asteroids can be mined for credits and you can make purchases at a space station (missiles, faster ship upgrades or more capacity for the Earth transports). Oh: missiles are the only thing that damage the engine so your infinite lasers are only good for asteroids.
Playing the game turned out to be kind of fun so I really wish I gave myself more time. Maybe I'll upload it to itch.io anyway after some balancing.
I was lucky to own great Synty assets for the graphics and find free music and sounds online. Thank you to everyone who shares their work for those of us who can only program!
(If you're curious, the three arrows coming out of the ship point to Earth, the station (which moves) and the enemy.)
