The PR description states "Navigate five levels of puzzles and traps" but the code only contains 4 levels (indices 0-3 in the levels array).

The move function treats ghost as a solid wall (line 329), preventing the player from moving into a ghost's tile. However, in afterInput, the ghost moves toward the player and checks collision after moving (line 436). If the ghost moves onto the player's tile, the player gets caught. But if the player moves toward the ghost, the player is simply blocked. This asymmetry means the ghost collision in afterInput (line 436) can never trigger when the ghost moves onto the player's current position in the same tick, because the ghost is also solid (set in setSolids), so g.x += moveX won't move it onto the player's tile either. The ghost and player can never occupy the same tile, making the ghost catch logic on line 436 unreachable. Consider removing ghost from setSolids or from the solid check in move, and instead handling ghost collision explicitly.

The @title in the file header is "Dungeon_Escape" but the file is named "BreakYourHead.js" and the PR title is "BreakYourHead". These should be consistent.

The @author is "Azmeer Pirani" but the PR description says the author is "Sudo-Aju". These should match.
