Super Motherload now has a series of 6 Trading Cards on Steam!
You can use each set of 6 cards to craft 5 badge levels in sequence. Also included with the Trading Card release are 3 backgrounds, 6 emoticons, and a booster pack.
We're currently working on improved music looping and functionality, as well as saving custom key configurations. These will arrive in a future update.
Let us know what you think of the new Trading Cards, Backgrounds, Badges and Emoticons.
