It’s reskinned D&D 3.5, very rules light. The stats are Strength, Dexterity, Fortitude (Con), Book Smarts (Int), Street Smarts (Wis) and Charm (Cha). Classes are called “Trots” (because you can trot however you want, and that’s OK, buckaroo!) Core classes are Bad Boys (Fighters), Sneaks (Rogues), Charmers (Bards), Wizards (Wizards) and True Buckaroos (Bard / Cleric / Sorcerer / Shit Chuck made up). Core races are Humans, Big Feet, Raptors, Unicorns and Living Motorcycles. The game rules state that “Due to the nature of the Tingleverse, it is not allowed to create a character under 18 years of age.” However, the contents of the book are very PG13… It’s up to you to decide how explicitly “real” you want to make “love” in your storytelling game. There is some very sparse lore about Billings Montana, the Void, the City of Devils (Los Angeles) and the rest of the Tingleverse. If you didn’t know the Tingleverse was a Stephen King parody, you will after reading the rule book. There are no “guns” (they were never invented in this timeline) and it seems to me the game would be fully compatible with any D&D 3.5 equipment list.
