I really love this gameplay concept of being able to swap the tiles to get the guy to the finish. One of the best puzzle game ideas I've seen in a while. Although I honestly feel like the timer resetting the level immediately kind of takes away from the puzzle aspect? It felt like I would sometimes be getting close to figuring a level out, then the level just resets. I think it would probably feel a lot better to play without the energy mechanic, but maybe a cool middle ground would just be disabling the time stop effect if you run out of energy? That way you can keep playing, but it becomes harder.
