Amazing models, very good job! The control scheme with the isometric view felt a bit wonky as others have pointed out but didn't take too long to get used to it - apart from some times where it felt like the character got stuck.
Was it supposed to be possible to move diagonally? When I discovered that was a thing all challenge disappeared from the puzzles. Was a perfect balance of difficulty (if aiming for 100%) when just moving in four directions.
