For a first game, especially one made in just a week, this is rather impressive- although I do admit I might just be too dazzled by the amazing art direction to be a good judge.
The gameplay was simple, but fair and fun, and had plenty of room for expansion if you ever wanted- I kind of expected for there to be some difference in the ending depending on how much stuff you broke/dropped, but it wasn't a bother that there wasn't.
The art was by far the strongest point though. A beautiful color pallete, expressive and fun mix of stylization and detail, cute ghost designs and a distractingly gorgeous human- this guy seems like he should be in a dating sim or something...
