Almost everything in this project is from Terraria, a game by Re-Logic. Credit is given. Changelog: 5/18/2019: Release. Only attack from the boss is Retinazer's laser. The boss does not have a proper health bar. Player does not have walking or jumping animations. Only weapon used by player is Clockwork Rifle. Nothing happens when either of the Twins reaches 0 health. After about an hour after release, a bug where Retinazer's lasers could be entirely avoided by going to the edge was patched. 5/29/2019: Added Melee attacks for both of the twins.
