Hahaha this is what I wanted for my visual novel project :) Let me know if you plan on adding en passant and promotion! I would love for the player to be able to play a simple but complete chess game against one of the characters in my game!
If it spices things up for you: I'm willing to pay like $100 for a full version with all available moves, choice of color, satisfying game sounds for move and capture, and a special sound for checkmate. Just contact me at minzart [at] gmail.com!
