oh wow nice rating, that legit lol. Yea I think it should be much quieter or use a different sound effect. Like for the 3rd puzzle theres a lot of unnecessary pieces (you really only need the queen + the bishop/knight).
Isnt Puzzle 5 (with 2 rooks vs 1 pawn) just a normal rook king vs king mate? i dont get what do the extra pawn and rook do.

This one had so many extra pieces i didnt know what to do with them lol

Was fun though, you did make a lot of puzzles. But it's probably more effective to play around with then engine until you find a puzzle than the opposite? idk!
