This is a fun, charming, and quick game. I've experienced it as both a player and a GM. As a GM, the barcode generation system immediately gives you the bones of a fun and quirky one-shot, but can also spin up ideas you could adapt to a larger campaign.
As a player, it's a curious (and hilarious) sensation to be dropped into the body of a character and to try to figure out who you are (without revealing that you don't know who you are). This creates a story with high stakes but low pressure on the player to know the rules or lore.
