First, I would like to say, this is an amazing game with a very unique mechanic. I played Salvage and didn't know there was a sequel until today!
Did you happen to write a list of enemies somewhere? I noticed there are many new enemies like the one with two bullets constantly orbiting around it and the one that charges towards you. Are those all of the new enemies? I would also like to find out their names, but don't want to die constantly. Maybe you can make a guidebook where every time you discover a new enemy, it shows the name, picture, and perhaps even some lore?
Also, what is the difference between a normal enemy and an elite enemy? I have only encountered an elite enemy once with the spotlight laser one and instead of a straight line, it created a circle. Do elite enemies have special behavior and attacks?
