the game is masterfully done in every aspect i can't criticise anything, my respects. BTW there is this bug that makes the cubes "fall apart" when you move them if i explain myself correctly. At first i thought it was harmless but it displaces the gem too and leaves the board in a state that it was clearly not supposed to be in, The glitch allowed me to beat a level in an unintended way and had me restart another so you should check that out
