The Legend of Bum-Bo certainly looks like a unique game, but it draws inspiration from a number of franchises you might know. Developer Edmund McMillen spoke to Gamasutra about what games paved the way for Bum-Bo.
“It’s mostly a mashup of games like Puzzle Quest and Plants Vs. Zombies spun in a way that makes it feel fresh and new. I took that foundation and pushed Isaac in as much as I could as far as resources structure, theme and RNG elements. ...the mechanics came out of a lot of trial and error with trying to make a dungeon crawler and a match game [that could] give us the same feeling as Magic: The Gathering.”
