After a few more camera experiments, I went back to the original camera. It seems to work best.
I've also finally implemented damage and fighter respawning. I've also placed some more turrets so the map is more challenging to play.
When talking to iNfraNe, he gave me the idea of generating the terrain randomly, like Rao_Dao_Zao
does. The more I think about it, the more I like the idea, so I think I'll be looking into that next.
