This game is pretty cool, I like the graphics and the gameplay concept of having the ghost repeat your actions.
However, this game has a major issue with readability. Even in the first room this was an issue, where the button was impossible to see, as was the arrow trap. The arrow was also really tiny and hard to see. It made it hard to tell what I was doing was affecting the level, like was it the box that was opening the door, or was it me standing on a switch, or was it my ghost standing on a switch? I couldn't even really tell if there was a button I was standing on since it kinda blended into the ground.
To make the stuff in the level more readable, I suggest either changing its color or increasing its size (i.e. there's a big square button that presses down when you stand on it). Also for the tutorial section, anything you make the player read should be utilized in that room, or else the player will forget it. (for me it was the shooting mechanic, I had to replay the game to figure out how to shoot)
Overall I can tell this game had a lot of love put in it and it has so many things going for it, such as the amazing graphics. But for players to be able to experience it, you need to work on making the players understand the game from your perspective!
