Really cute art style and music. I liked the little "redo controls" panels idea, good for the puzzle aspect!
I enjoyed solving the puzzles.
I had some trouble with the perspective, sometime's I wasn't able to tell what was aligned and what wasn't, and what direction the ghost would face. It seems the W and S key do nothing.
Also, the last puzzle I glitched the solution by holding D while the platform was moving, throwing me outside the level.
But good job!
