Hey! I gave your game a play and had the following thoughts:

1. I love the idea of using two versions of myself to navigate different parts of the levels. I also liked the special abilities of the ghost to basically break physics and do anything I needed to do, so long as I do it fast enough

2. I was confused how to use the ghosts controls at first. I kept trying to go up with the spacebar, and didn't realize I could float in any direction.

3. I got stuck on level 2 and couldn't get through it

4. You did a lot of stuff with a very limited amount of visuals, and I commend you for that!
