Reward Keys
Reward Keys collected during a cave run can be used at the prize machine or sold after the run.
Collecting keys
Keys appear during runs and can be included in chest rewards. Token of Remembrance grants some keys per run and Key Magnet attracts them.
After the run
The prize machine consumes keys to open eggs, or sells remaining keys. The checked Prize Machine scene sets the sale value to 300 coins per key. Released-platform parity remains to confirm.
