It was really fun, for some constructive comment:
The first little tutorial text does not really precise the direction you're going is the direction of your cursor, so I for almost a minute, I got confused stuck on a wall
And in term of level design, I finish by almost always hugging walls, if will be probably better to have more ghost close to the walls and less in the middle of the room, so player are forced to correctly avoid them
It was also a bit hard to activate the clock save point, each time, took me multiple click before I manage.
Beside that, the game was really fun, the rythmic music is good and visual are pretty.
