this does look cool. Why do you have two different types of enemy ships btw?
I used to work in linux too, not anymore. If you have any problem in linux you just google it or ask around. it does take a while to get used to it but linux is significantly faster to work with.

Enemy Ships 1 was when I first started making the game. Then I changed the game completely to a faster more arcade style shooter. So, I ended up making different enemy types and created new variants. For example, SB_Kamikazee will charge at the player ship and blow up. SB_Sniper will hang back, pinpoint with a laser and shot at the player ship from far away.
