Cute game. The controls felt nice and I liked the fact you added new mechanics like balloons and angel wings to mix things up. I felt the level was too long though.. The percent bar was moving so slowly that I felt I'd be wondering around for ever looking for food. I almost quit and then I found the angel wings which made me zip about much faster which was great. Then I lost the wings on some spikes and that was enough to make me give up as my percent bar was only on 21% :( Also, why do spikes kill a ghost??
The characters we cute but the level could have more variety like different terrain in certains areas, or make certain areas darker, you could even make an area of the map completely black and give your ghost a glow feature that lights up the area around them... just a thought.
PS. playing this made me hungry :)
