Nice game.
1, I don't think the theme is interpreted to well. You can just have the hunger meter as a standalone.
2, There is a glitch where if two enemies overlap. Then You collect both but only one appears in a bubble.
3, There is a similar glitch where you can collect two food items and if you feed Velma those two food items. If there is even one Item that is not on the order list. She will get angry, even if you have a item on that list.
Besides those, I think It can be a nice party game someday.
Also, I would be very happy if you would play my game.
