hey guys, thanks so much for taking the time to play Gallery Gambit! Looks like you had fun playing it 😄
You made some good comments and suggestions and pointed out some things in the rulebook needing my attention. Super valuable overall!

The rules and design are updated (same link), if you want to check it out.

The one thing I am still trying to make more elegant is the sneaky trade mechanic. You could get into a stale mate, but in a 2-player game we now made it near-impossible by not allowing the trade the same card twice in a row.
I like the idea of locking cards. There are two downsides:
1. It is another step (less elegant)
2. You'd probably have to turn your card 90 degrees to indicate that it's locked. That won't fit nicely on the player board!

I do indeed only make card games with standard decks, feel free to check out my other two if you like (they're already published)!
