so what's different?

they're both pretty much the same for the most part, the main difference is in the military training part of the game, where instead of pressing the same button 9 times to get double damage, you have to upgrade parts of your military, like the army or space force, each giving you a 5% chance to do double damage, get all 11 to max (each has 3 levels), and you'll always do double damage!

the rest of the changes were just quality of life (for both you and me) as well as updating the starting screen and adding a game over stats screen.
