Invincible suggested Apex Predator as a theme for weekly challenge.
I wanted to throw out Candyland as a suggestion :3
Some suggestions that are a little more mundane and generic:
* Interface designs
* Parallax looping backgrounds
Apex Predator is a bit vague, but sounds good! monsters incoming!!!
Cards, both front and back (especially trading cards - there is only one trading card design that I could find on here!)
That's funny~ I'm messing around with some card ideas :3 A card game is in my soul. lol. Yay for interactable rectangles <333 filled with crazy art and rules.
