Allow choice between Face Up and Face Down swaps #5
Description
Context
The results of player feedback suggest that Face Up swaps give too much information too fast.
On the other hand, Face Down swaps both significantly slow down the game and remove a lot of the strategic consideration around which swaps to prioritize.
Proposed Solution
Consider stealing the idea of "information tokens" from Hanabi so players are limited in the number of Face Up swaps they can make. Additionally, adding ways to replenish "information tokens" may increase the range of interesting strategies.
Relevant Code
The swap logic currently lives at https://github.com/shaoster/uncovered/blob/master/src/game.js#L115 though which type of swap is active is currently toggled by a static game mode.
Note: Adding this as a game mechanic might first require #3 be resolved so the player has a way to indicate which type of swap they'd like to perform.
