Greetings All! Thank you for your feedback on my game thus far, I've taken suggestions that are within the scope of the rules for making updates and have applied those. Fixes include:

Start and End screen are no longer by-passable immediately. There is a 3 second timer so you can just spam click your way through it.

Power Warning no longer plays continuously. It instead plays every 5 seconds. Much less annoying.

I re-balanced variable settings. Things ramp up a bit faster now.

There was a math issue for damage when a ship collides with your base, this has been corrected and power use has been balanced a bit around it.

Hit boxes are a bit larger than they were on the enemies

There is still no final score on the game over screen, I didn't get time to include that during the contest and feel it is likely out of scoop for the rules post jam. I'm planning on continuing to develop this game to a more finished product so look for a post jam version in the future.
