I think I understand how this works. This is a cool game base! It's a very loose interpretation of loop, but I definitely like that you did a "board game" type of video game. I also like the fact that there is just a shotgun for no reason. However, after playing a few times, the gameplay started to get a bit boring. I would recommend adding in something else if you continue this game, such as varying board sizes or time limits, just to add a bit more strategy to the game if it is harder to count the gems your opponent makes. Great job though, it's a charming little game.
