Browse possible checks, rewards and settings. What appears in your game depends on your World options.
31 tracked actions: 22 stage clears, four secret exits and five additional interactions. The selected goal locks one action to completion, leaving 30 shuffled rewards by default. Both goals lock two actions and leave 29 rewards. The catalog includes both actions because each can be an ordinary reward under the other single goal.
