This is such an interesting spin on the chess genre! I'm curious to see what kind of strategies and techniques like specific openings and tactics players can use to get more bottle caps! Maybe you can have a lessons page where players can learn techniques on how specific openings and strategies can be played, like how moving bottle caps a specific side or moving them all in a specific spot can help get more pieces? Maybe you can also add a leaderboard where the more stacked caps you have total, the more points you can earn too? Maybe also a ranked mode where you can play other players? Either way, very interesting idea and would love to see more be made with this! Good luck with the rest of your jam!
