Here's a very simple, friendly, bouncy sort of poster font floating somewhere in the realm between funky and groovy and goofy and cartoony (which, on the map, puts it just south of the river here in Austin). I built Invader Candy from hand-drawn doodles, smoothed it a bit digitally, and called it good.
Invader Candy is an all-caps poster font with letters, numerals, and a few assorted punctuation marks. Enjoy!
