Well, after suggesting the boss battle, I finally finished it off. It is inspired by a certain boss battle from Copy Kitty. This boss fight was supposed to be appended to a level called "Destroy to the World", but I haven't yet figured out how to make the level yet.
05 November 2013:
- Ensured the third Cat Pillar spawns properly.
- Replaced "Wart" with "Mother Brain" and the three "Mother Brains" with NPC-208.
- Boss might be too easy once the "Cat Pillars" are destroyed.
- Second form's boss music is definitely copyrighted. Wish to replace with a menacing/orchestral version of Episode 3 opening theme.
