Galaxy Defender 2: Lesser Evils

My modifications:

- 3 distinct levels, with a boss fight at the end

- intro "levels" with text to provide a story to the game

- adjusted pitch of provided music to add unique moods to each level/intro

- added code to make droppable items that enemies carry and drop when defeated

- added new layers to the tile hierarchy to add depth and design to non-interactable items in the environment 

- modified the colors of the in-game menus

-Enjoy!
