Clues were going to be an out-of-combat resource that had multiple uses! They would open other paths along the map, allow you to skip certain specific combat encounters, or be used to re-roll after combat card rewards(which were also not implemented). I also had a few card interactions that would scale with the number of clues you had. However, I very clearly overscoped how much I would be able to accomplish.
I'm glad you enjoyed the puns! Thank you for playing!
