I didn't expect to have fun but honestly i enjoyed your game, especially the difficulty. Your levels are quite well built and i never felt lost, so it's a good point ! I would just recommend to pimp up your graphics a bit with particles or animations, and also make the game a bit more clear like having marks to tell where the ghost is, or where to click to move (i died a lot because of that last point xD)
It's a good starting point in my opinion so keep it up !
