The art was great, the story was great and even the little cursor that became a happy face was a nice touch. Didn't see the end coming even though there were several clues around the area (Like the poster, which i only realised while editing.) I thought it was a pretty straightforward game and was a great short game to play.
The only thing I would suggest is maybe spooky things that would lead up to the end; finding the head in the fridge. Like maybe some suspicoius lines of nothing being able to sate your hunger or some interesting tools around the kitchen that wouldn't normally be there or maybe some 'ketchup; on the counter or something like that.
But yeah, it was a blas tot play and had fun with it. Especially since I didn't know what to expect, was taken aback by the end. Overall a great game and you'e done a great job on it!
