The scripts are pretty fun. I've got two issues though, the first being your use of angular velocity.
ahhhhh
The second issue is that your boss' hitbox is too small. For SetCollisionA, you'll want a larger radius than the actual sprite just to make things simplier and for consistant damage. For SetCollisionB you can have it the same size as the sprite, so that the player doesn't get a "clipdeath" by running by the boss. Right now my shots don't do very much damage unless I'm dead on with the boss' x-coordinate, and even then I'm not hitting all my bullets with any character.
Confusing Prejudice was my favourite of the lot, good variety and fun to play.
Also what the hell guys do you want me to turn into a tomato or what
