The game supports up to four-player local cooperative play on most platforms, except for the 3DS version. Reception and Critique
Players can choose from characters including Finn, Jake, Marceline, Cinnamon Bun, Ice King, Flame Princess, and Lumpy Space Princess.
The dungeon consists of 100 randomly generated floors with boss battles occurring every ten levels. Players collect treasure to buy stat upgrades in the surface hub, though death results in losing half of their current cash.
Prisoners have been mysteriously escaping from a dungeon deemed inescapable. Bubblegum admits she "doesn't know" why, prompting the game's title.
The game ends with the revelation that Bubblegum is 827 years old, a fact that shocks and horrifies the Ice King. Gameplay Mechanics
