Use the arrow keys to move. Every chess piece functions differently. Pawns can jump (up arrow.) They can jump really high below y=0, but really low after that. Knights can walljump. Rooks are very fast and they can teleport upwards (up arrow.) Bishops dash left and right (with left and right keys; they replace your normal motion.) Kings can double jump. Queens can fly (like a top-down.)
Images by Clker-Free-Vector-Images (pixabay) All levels are possible. Pawn Exp: Pawns start with a double move. Knight Exp: Knights can basically always jump. Rook Exp: Rooks can travel upwards instantly. Bishop Exp: Moves like a bishop... King Exp: Kings kinda have a barrier around them for the other king. So if you toggled that midair, then the barrier becomes part of your hitbox and you can jump again. Queen Exp: Can move in any direction.
