These are three jellyfish I designed. They are supposed to be pickups that the player collects, so I made them as non-threatening looking as possible. They are based directly off of pictures of jellyfish I found
These are two animations I created using previously designed sprites and Photoshop's Timeline editor. I then exported them as PNG image sequences so they could be imported into Unity.
This is a pufferfish intended to represent a static obstacle for players. It looks sufficiently scummy and hostile.
This is the image that will appear when a player completes a stage. There is also an animated 'COMPLETE' text that I created, though I don't believe the team can import it into Unity properly.
This is a simple color edit of a previous background image to be used for later levels.
