Gameplay: Functions and works consistently within itself. No bugs. Good job!
Creativity & Innovation: I'm unable to comment on this. The gameplay itself is fairly standard walking sim sidescroller, but the large swaths of the same background without anything to interact with ends up obfuscating everything else.
Theme Adherence: Unable to say.
Playability & User Experience: Direct controls that were easy to understand, and also communicated to the player, great job on that. The bigger problem is that there is too much dead time, and the pixel art text is very difficult to read.
Art and Design: Solid pixel art. The ghosts are very endearing.
Overall Fun Factor: I'm not sure for this one. I expect there's something there, but it buries the lead too much.
As an overall comment: While twists and shocks are good and engaging, you can't neglect to keep the player engaged enough for them to experience those critical moments. With this, it could be higher enemy density, or even just more variance in background assets and their placement.
