This hack intends to clean up the graphics so they are easier to identify (especially the power-ups) and better match the aquatic theme. Most of graphics were left unmodified because of their higher quality. The mermaid is censored for less controversial play around children. The introductory text is altered to clarify the merfolks’ motivations and also to clarify your mission.
