Chess Game With Fully Custom Engine!

[Azmor]

Hiya, I've been working on a Chess game via Love for a while now and I'm excited to say I've released it, It's on Itch.io and it's fully free, feel free to try it out!

As someone who worked on a Chess implementation for a Luanti mod before (modelled after the FIDE Laws of Chess from January 2023), this triggers some obvious questions:

Does en passant work?
Does castling work?
Does the 50-move rule work?
Does the 75-move rule work?
Does the rule of threefold repetition work?
Does the rule of fivefold repetition work?
Does the game detect all possible dead positions? (If yes, then I’m impressed, but I doubt it. This is hands down the hardest feature of Chess to actually fully implement in Chess engines, which is why many don’t even bother)
Does the game detect at least well-known dead positions and trigger a remis (king vs king, king vs king and bishop, king vs king and knight, king and bishop vs king and bishop while both bishops stand on squares of the same color)?
Can players choose to which piece to promote?
Can players agree to a draw?
Can players resign?
Is the game free software? (I don’t see source code or a free software license of your code )
