The visuals are fantastic! I have a couple of small suggestions:
1. It would be great to add some alignment detection when platforms end their movement. Otherwise, the player character can easily get stuck.
2. Consider increasing the movement speed of the character slightly. In normal circumstances, players may not have the patience to wait for the character to slowly reach the end point.
If this is a puzzle game, I recommend adding a pause option so that players can still have time to think and adjust their moves while the character is moving. If this is a reflex-based game, I suggest implementing direct mouse dragging instead.
Overall, it's a fantastic game and I had fun playing it.
